Published: December 2020

Abstract
With the growing revolution in technology, quality is always being considered a major point of concern and developing countries like India where number of small and medium enterprises are working contributing for major part of employment, these quality concern need to be focussed. The present work involves the case study which has been conducted in one of small scale industry dealing with chemical processing, in Nagpur. The objective is to find out the solution for one of the problem discussed by production manager of the company. The problem is related to feeding of raw material into the processing plant which have been done manually and cause of quality issue and serious work hazard. So we have suggested a design of setup of feeding mechanism for pouring the raw material. While designing, first the survey has been conducted where it was found that different types of hoppers are available in market based in different size and shape. The hopper which we supposed to design should fulfil the requirement of the manager and all the technicalities. In order to do so we have studies number of design parameter and formulate the design procedure for each and every aspect right from calculation of mass flow rate, hopper angle, exit rate, wall friction angle, design of bevel gear, different force acting on hopper surface. The design of the hopper and the complete setup for the pouring resin is carried out by considering only porous raw material. So, comprehensive approach for designing the hopper as a solution have been done and proposed to company. Similarly the design is being validated using ANSYS software package.

Abstract
The current work studies the effect of adding chopped carbon fiber (CCF) on gypsum plaster properties (precisely the compressive strength and the modulus of rupture). The research plan consists of using six mixes of gypsum plaster; these mixes are divided into two groups according to the (Water/Gypsum) ratios (0.5 & 0.6). Each group was divided into three subgroups according to CCF volume fraction (Vf): 0.0%, 0.2% and 0.4%. Three cubic (50×50×50) mm and three prismatic (40×40×160) mm samples were performed for each mix. It was found that, the addition of CCF to the gypsum plaster mixes increases both the compressive strength and the modulus of rupture for both (W/G) ratios, and the percentage of this increase is enlarged with increasing (W/G) ratio. On the other hand, when (W/G) ratio is enlarged, the compressive strength and the modulus of rupture is deteriorated for all (Vf) of CCF, and this percentage of deterioration is decreased in the presence of CCF.

Abstract
The manuscript discusses about the effect of compressive load on the E-Glass fiber reinforced interpenetrating polymer networks (IPNs). In this work, a series of combination of vinyl ester (VER) loaded polyurethane (PU) IPNs have been taken as the matrix material with the E-Glass reinforcement, with the loading of 0%, 10%, 20%, 30%, 40%, 50% PU respectively. Besides hand-layup technique was used to fabricate the cylindrical shells in order to get the final shape of the IPN composite pipe. Simultaneously to validate the compressive strength behavior of the IPN composite pipe, experimental analysis was carried out as per the ASTM D695 standard at normal room temperature to extract compressive strength value of the PU loaded IPN composite pipes. During this test, it was observed that physical strength of the composite pipes reduces gradually as much as PU addition into the IPN composite pipe increases. Surprisingly, another important notification was that, the geometric structure of the composite pipes is not affected as like as the crushing observed on the pure VER pipe. As much as loading of the PU into the IPN, increases the structural integrity of the composite pipes in outstanding (retains structural ability) manner. Further the experimental analysis values are validated with numerical analysis software ANSYS, obtained values and numerical values are shown good agreement each other.

Published: December 2020

Abstract
Abrasive wear is of particular importance in various ground-engaging applications and the necessity of tools with high wear resistant materials has increased exponentially to extend the life span as well as to reduce the cost involved in manufacturing. This work is mainly focusing on the development of wear resistance for the aforementioned ground-engaging applications. An overlaying alloy (stellite 6) in the form of electrode form was used to coat the mild steel of grade C-45, which was used as the substrate material. The wear behaviour was characterized using a Pin-on-Disk test setup in a dry condition. A correlation between the size of overlaid material and the size of the C-45 material was observed by an optical microscope and observed that the presence of the CoCr alloy matrix significantly improves the wear resistance. The presence of the CoCr alloy matrix is found to enhance the wear resistance by reducing the rate of wear of the material. The results show that the increasing coating thickness increases the hardness of the material and the significant improvement in the wear resistance with coating.

Published: December 2020

Abstract
In this work, the effect of Calcium Carbonate (CaCo3) particulate filler on the mechanical properties of the coir fibre/Epoxy composites was studied. Calcium Carbonate was incorporated with Coir/Epoxy at different weight percentages such as 4%, 8%, 12%, 16% and 20%. Composite specimens were fabricated by incorporating surface-treated coir fibre at 15% fibre loading and powdered Calcium carbonate. Coir fibres were treated by 2% NaOH solution to improve the surface adhesion. Hand layup method was employed to fabricate the composite samples. As per ASTM standards mechanical properties were evaluated on specimens. The results indicated that the addition of CaCo3 on coir fibre/epoxy resin up to 16% filler loading could improve the tensile, flexural and impact strength. The mechanical properties were reduced by adding more than 16% of CaCo3 filler to the composites. The test results indicated a marginal increase in mechanical strengths and a relatively significant improvement in the mechanical moduli. SEM images of the tensile test samples were taken to study the surface morphology.

Abstract
In this study, corroded reinforced beam specimens failing in bending were strengthened using near surface mounted (NSM) technique and evaluated. Two types of glass fiber reinforced polymer (bar, mat) were investigated for the strengthening materials. A simulated corrosion rate of 25% was considered in the study. The maximum recorded load of the strengthened beams with GFRP bars showed enhancement in the ultimate strength which reached 89% of the undamaged control beam strength. While using of GFRP mat for strengthening the corroded beams increased only the ductility but had negligible effect on the improvement of ultimate strength. The results indicated that using near surface mounted technique prevents the occurrence of de-bonding failure which results in an enhancement in the crack load and failure load of the tested beams.

Abstract
Aluminium metal matrix composites are generally produced employing stir casting technique. The effect of stirrer blade on stir casting of aluminium composite with 12 wt% SiC, 4 wt% magnesium and 2 wt% copper was observed. The composites were prepared with 6061 base metal using three different design of stirrer blade which created different vortex fluid flow while stirring. Due to high density of SiC particles, it tries to settle in lower part of the molten metal matrix. Hence change in vortex technique by stirrer design modification can have influence on the mechanical and microstructure behaviour of the composites. The aluminium SiC composite are evaluated by mechanical properties and microstructure analysis based on stirrer blade design used while stir casting. The change in blade stirrer shows variation in testing tensile strength and hardness. The optical microstructure and SEM images were observed to analyze the cast structure and reinforcement distribution in the composites. The SiC particles were appeared to distribute along the grain boundaries of the composite and also cast defects were observed. Composite prepared with alternate peddle blade produced best mechanical properties.

Abstract
In a wind turbine, blades are the most important component of wind capture in wind turbines as they easily become unreliable due to environmental conditions. This paper demonstrates the malfunction characterization of wind turbine blades by the use of vibration data via the credal decision tree (CDT). The defects on the blades are replicated to model the defects through machine learning. The extraction of functions (statistical functions) and the selection of the component (algorithm of decision tree J48) were employed to identify the best framework for defect classification. Using the credal decision tree, 82.67% of classification accuracy have been obtained with the Kappa statistic of 0.792 and mean absolute error of 0.0768.

Published: December 2020

Abstract
Rubber processing manufacturing facility uses an injection moulding machine for its primary operation. This machine is fully automatic with one manual operation requiring two operators to push and pull the sliding tray during loading and unloading process. This work aims in eliminating the only manual operation by designing an automatic sliding rack system. As the weight of the sliding tray is 600 kg, it requires more effort from the operators resulting in fatigue. In few instances, minor injuries have been reported when the operators accidently get in direct contact with the finished components during loading and unloading. During the design process, rack and pinion mechanism is considered for the automatic sliding of the rack. The pinion is attached to the motor and the rack will push/pull the sliding rack as per the requirement. The design of all the components of the sliding rack system is performed in Unigraphics 2007. Also, the simulation studies shows that the cycle time is reduced from 9.67 seconds to 5.52 seconds. This shows the significant reduction in the cycle time.

Published: December 2020

Abstract
The wind energy is more reliable, clear, and easilyexploitable form of renewable energy source. Wind turbines are being stationed to capture the wind’s power and convert it to electricity. The wind turbines are operated at rated speed to ensure smooth operation. When the wind turbine faces the higher wind speed, wind forceimpacts the tower head causing immediate damage the turbine blade. Wind turbines are equipped with various Aerodynamic braking systems and mechanical braking system to control the over speeding of the wind turbine rotor at extreme wind velocity. In this novelmethodology, it is attended to reduce the rotational speed of the wind turbine aerodynamically by providing the chord wise slot (opening). The slot modifies the pressure distribution over the upper side and lower side of the turbine blade that slows down the rotational speed of the wind turbine within the safe limit. In this present attempt, the over speeding of the wind turbine rotor is effectively controlled without disturbing the power generation. The different parameters of the slot such as the position of the slot, inclination of the slot, and width of the slot are studied and the slot parameters are computationally optimized.

Abstract
A newsboy problem is a specialized form of a general inventory problem which discusses the decision making skill of a trader, a retailer to be specific, who is facing uncertainty in the form of the demand of one or more perishable products. The lifetime of a perishable product depends on the domain. Products like newspapers, flowers are single day products as they are invalid or less useful after one day. Products like vegetables, fruits may be considered for two or three days depending on the storage procedure employed. So, the retailer has to dispense off the products within their lifetime, either by selling it or by salvaging it. This has been one of the most interesting and sought after problem for discussion as it provides with a simplistic platform to start the discussionsand hence the literature is huge for such problems. It has been analyzed using very many avenues in the literature. This paper discusses the problem of the retailer, dealing in two perishable products using Monte Carlo Simulation and compare its efficiency with standard theoretical Fractile method.
