Friction stir spot welding (FSSW) is a very important part of conventional friction stir welding (FSW) which can be a replacement for riveted assemblies and resistance spot welding. This technique provides high quality joints compared to conventional welding processes. Friction stir spot welding (FSSW) is a new technology adopted to join various types of metals such as titanium, aluminum, magnesium. It is also used for welding polymer materials which are difficult to weld by the conventional welding process. In various industrial applications, high density polyethylene (HDPE) becomes the most used material. The parameters and mechanical properties of the welds are the major problems in the welding processes. In this paper, we have presented a contribution in finite element modeling of the friction stir spot welding process (FSSW) using Abaqus as a finite element solver. The objective of this paper is to study the HDPE plates resistance of stir spot welding joints (FSSW). First, we show the experimental tests results of high-density polyethylene (HDPE) plates assembled by friction stir spot welding (FSSW). Three-dimensional numerical modeling by the finite element method makes it possible to determine the best representation of the weld joint for a good prediction of its behavior. Comparison of the results shows that there is a good agreement between the numerical modeling predictions and the experimental results.

Authors: Konieczny Mateusz , Achtelik Henryk , Gasiak Grzegorz
Published: December 2020

The paper presents the stress distribution along the plate thickness in a bimetallic steel – titanium circular, axially symmetrical perforated plate produced in the technological process of explosion welding. The steel layer is the layer that transfers the load in the plate, while the titanium layer is used to improve the properties of the plate, e.g. corrosion resistance, thermal transmittance, etc. in the plate. Two cases of fastening were considered, i.e. a freely supported and fixed plate. Such plates are used in various engineering structures, e.g. simply supported plates can be used in loose material screens, while plates are fixed in heat exchangers. The load was assumed as a concentrated force applied perpendicularly to the plate surface. The results obtained numerically using the finite element method were compared with the results calculated according to the analytical equations. It has been shown that the difference in the results of equivalent von Mises stress calculations does not exceed 13%. The research results presented in the paper can be used by engineers to design bimetallic perforated plates perpendicularly loaded to their surface.

Published: December 2020

In this paper thermal analysis was applied to determine the “Critical Stress” of concrete, different from its ultimate strength, able to produce the first damage in the structures under compressive loads. The Critical Stress can be thought as the stress able to produce the beginning of fatigue rupture within the material. Several specimens of high strength concrete were tested in order to define the incipient crack phenomena, also in internal part of the specimen not accessible by direct inspections, with the aid of infrared thermography. A finite element analysis completes the study and compares, for the same static loading conditions, the stress state with the experimental thermographic images. The final results show as the coupling of normal compressive test and the acquisition of the thermal images can be a useful aid to estimate a security stress value, indeed the Critical Stress, before the Ultimate Serviceability Limit (SLU) of the structure, defined as the maximum load condition before its failure.

Development of floating breakwater technology is increasing along with the rising interest of floating infrastructure. Different kind of materials and shapes were researched for optimizing the performance of floating breakwater. In comparison of structure with a similar dimension, the more rigid one gave a better performance. Large and rigid structure are possible to construct with the usage of concrete. However, when there is a limit to the structure dimension, whether it is caused by construction or transportation method, the alternatives for improving performance are needed. This research proposed a double configuration setup to cope with the said limitation. The breakwater performance is tested with physical model in laboratory by comparing performance of single pontoon with double pontoon for various structure spacing. Pontoon size are 1.2 m in length, 0.3 m in width, and 0.15 m in height and tested with many combinations of irregular waves. For double configurations model, the spacing of 30 cm, 60 cm, and 90 cm are used. Based on tested result, there are improvement up to 20% by using the double configuration. The improvement determined by ratio of structure spacing with wavelength. Larger ratio resulted a better performance in condition where the spacing did not exceed 0,65 length of wavelength.

Shoaling due to sedimentation process leads to the problem of port operation, where ships have a problem to navigate inside the port. The problem of the operation can lead to the reduction of the profit margin for the port. This paper discusses the engineering solution to solve the sedimentation problem because of the estuary inflow. In order to analyze the sedimentation behavior, computational model deploys as a tool for the assessments. The simulation results are validated by observation data; water level observation one month and current measurement for fifteen days. Simulation results show that the sedimentation in Tanjung Mas port mostly because of estuary inflow in the West and in the East side of the port with maximum suspended sediment concentration around 0,15 kg/m3. Sedimentation problems can be solved both by dredging and refunctioning of the breakwater. In the dredging process, the existing dumping area has an appropriate location since the sedimentation dispersion still in the offshore area. Refunctioning of the breakwater can also reduce the sedimentation effectively, it is shown by morphological model results where siltation process both near the navigation channel and inside the port can be blocked by the structure.

Listvenites: new insights of a hydrothermal system fossilized in Cerro Matoso peridotites, Montelíbano, Córdoba Department, Colombia
Authors: Castrillón Andrés , Guerrero Javier
Published: December 2020

The products of metasomatic alteration (e.g., carbonation) of peridotites are called listvenites. Based on a description of the outcrops in the laterite deposit at Cerro Matoso located in the NW of Colombia, the mineralogical composition confirmed by petrography, and a chemical analysis performed with XRF and WDS/EDS, the previous unit called tachylite is redefined as listvenite. Two types of listvenites are described: listvenite A, with the mineralogical association of quartz + siderite + phyllosilicates + goethite +/- magnetite, and listvenite B, with the association of siderite + phyllosilicates + goethite. Cr-spinel relics accompanied by Mn-siderite and neoblastic textures, indicate their origin from peridotites, where Mn-Fe would have been deposited by hydrothermal fluids. Hydrothermal reducing environments with alkaline fluids and low temperatures should have favored the formation of listvenites that are observed along a fracture zone, oriented WNW-ESE at Pit-1 in Cerro Matoso. Due to exposure to climatic conditions since the Eocene, but definitively since the last Andean Orogeny, listvenites were affected, like all the rocks in the Cerro Matoso deposit, by intense supergene weathering and leaching processes, which could make their true origin unclear.
Review of geothermochronological and thermobarometric techniques for the construction of cooling and exhumation curves or paths for intrusive igneous rocks
Authors: Cetina Lina María , López-Isaza Julián Andrés , Cuéllar-Cárdenas Mario Andrés , Forero-Ortega Anny Julieth
Published: December 2020

The present study reviews radiometric and thermobarometric techniques used to construct cooling curves or paths to characterize intrusive bodies and to calculate cooling and exhumation rates. To construct these curves or paths, the temperature, time and depth variables must be estimated in intrusive bodies by applying various analytical techniques, including thermobarometry and U-Pb zircon, Ar-Ar hornblende and muscovite, fission track and (U-Th)/He zircon and apatite dating, in combination with a geological framework of reference for each intrusive body. The authors recommend to determine the crystallization age by zircon U-Pb dating, to quantify the emplacement depth using thermobarometry methods according to the composition of the intrusive body, to calculate the initial cooling ages with hornblende and muscovite Ar-Ar methods, as well as to calculate the cooling/exhumation ages in the upper crust using low-temperature thermochronology methods. These cooling curves or paths in intrusive bodies are highly relevant when studying compressive or extensional areas because they partly represent the thermal history of the era, thereby providing data on the magmatic and tectonic evolution of the region. Thus, these studies are highly important for designing geodynamic models and for their possible application in developing the tectonic model of the country.

Türkiye’de Finansal Gelişme ve Ekonomik Büyüme İlişkisi: RALS-EG Eşbütünleşme Testi
Authors: EYÜBOĞLU Kemal , AKAN Kadir
Published: December 2020

Bu çalışmada 1980-2016 dönemi için Türkiye’de finansal gelişme ile ekonomik büyüme arasındaki ilişki araştırılmıştır. Literatürde finansal gelişme büyüme etkileşimini araştıran çok sayıda çalışma vardır. Ancak önceki çalışmaların birçoğunda finansal gelişmeyi temsilen özel sektöre sağlanan kredilerinin GSYH’ye oranı, borsa kapitalizasyonunun GSYH’ye oranı veya M2 gibi değişkenler kullanılmıştır. Ancak, bu göstergeler finansal gelişmenin karmaşık çok boyutlu yapısını dikkate almamaktadır. Bu çalışmada literatürden farklı olarak finansal gelişmeyi temsilen Uluslararası Para Fonu (IMF) tarafından hesaplanan finansal gelişme endeksi verileri kullanılmıştır. Değişkenler arasındaki uzun dönemli ilişki Engle-Granger (1987) ve Lee vd. (2015) tarafından geliştirilen RALS-EG eşbütünleşme testleri ile analiz edilmiştir. Engle-Granger eşbütünleşme testi sonucu, değişkenlerin eşbütünleşik olmadığını gösterirken, RALS-EG testi sonucu ise değişkenlerin eşbütünleşik olduğunu ortaya koymuştur. Ardından uzun dönem katsayıları tahmin edilmiş ve finansal gelişmenin ekonomik büyümeye pozitif katkı sağladığı belirlenmiştir. Ayrıca yapılan Granger (1969) nedensellik testi sonucunda finansal gelişmenin ekonomik büyümenin nedeni olduğu saptanmıştır. Elde edilen bulgular arz öncüllü hipotezin Türkiye’de geçerli olduğunu göstermiştir. Finansal gelişme ve büyüme arasında bulunan bu ilişki, politika yapıcıların büyümeyi teşvik etmek için finansal gelişmeyi sağlayacak bankacılık sektörünü ve sermaye piyasalarını geliştirmeye yönelik gerekli düzenlemeleri yapmaları gerektiğini göstermektedir. Farklı finansal araçlara sahip derin ve likit bir piyasanın olması ülkelerin finansal şoklara karşı direncini artırmaya yardımcı olacak ve finansal istikrarı da teşvik edecektir.

Natural sand is extracted using mining methods, even for the manufacture of artificial sands. Sand is widely used in several areas. As construction aggregates; material processing industries; water and sewage treatment. The Areal of the company Morro Branco, where the sand samples were collected, is located around the headquarters of the municipality of Porto Grande. The municipality of Porto Grande in Amapá is located in the center of the state 108 kilometers from the capital Macapá. The objective of this research was to make the technological analysis of material from Areal Morro Branco, Porto Grande, Amapá, by fractionation. The sand was removed from a sandy area in the municipality of Porto Grande – AP with the use of hand tools for collection. 03 (three) samples from different points with different composition were collected, due to the existence of organic matter in its composition. Sodium silicate with a concentration of 10% and bromoform was used for the breakdown of the organic matter of the sample. These procedures were determined in the dry sample in an oven for 24 hours at approximately 110ºC, and the percentage of humidity (%U), this, was also determined in the original sample. It was verified through the tests and procedures performed that the moisture of the sand of The Areal Morro Branco is influenced by the organic matter resulting from the forest areas and water resources of the surroundings of The Areal. The granulometry of the points from which the sand was collected in the sand has characteristics of angled and sub-angled grain. With the aid of bromoform density, it was feasible to realize that the sand from which the sample was collected has quartz aggregates, feldspar with a density lower than 2.89 g/cm3. It has been suggested that the sand may also have mineral derivatives of sand with density greater than 2.89g/cm3, which are Olivine and Pyroxene.

Природный песок добывается методами добычи, даже для производства искусственных песков. Песок широко используется в нескольких областях. Как строительные агрегаты; отрасли переработки материалов; очистка воды и канализации. Areal компании Морро Бранко, где были собраны образцы песка, расположен вокруг штаб-квартиры муниципалитета Порто-Гранде. Муниципалитет Порто-Гранде в Амапе расположен в центре штата в 108 километрах от столицы Макапе. Цель этого исследования состояла в том, чтобы сделать технологический анализ материала из Areal Морро Бранко, Порто-Гранде, Амапа, путем фракционации. Песок был удален из песчаного района в муниципалитете Порто-Гранде – AP с использованием ручных инструментов для сбора. Из-за наличия органического вещества в его составе было собрано 03 (три) образца из разных точек с разным составом. Силикат натрия с концентрацией 10% и бромоформом использовался для расщепления органического вещества образца. Эти процедуры были определены в сухом образце в духовке в течение 24 часов при температуре около 110oC, и процент влажности (%U), это, также было определено в первоначальном образце. Было проверено с помощью испытаний и процедур, проведенных, что влажность песка Areal Морро Бранко находится под влиянием органических веществ в результате лесных массивов и водных ресурсов окрестностей Areal. Гранулометрия точек, из которых песок был собран в песок, имеет характеристики углового и подукорного зерна. С помощью плотности бромоформа, было возможно понять, что песок, из которого был собран образец имеет кварцевые агрегаты, feldspar с плотностью ниже 2,89 г/см3. Было высказано предположение, что песок может также иметь минеральные производные песка с плотностью более 2,89 г/см3, которые оливин и пироксен.
