Published: March 2019

Abstract
A dust explosion occurs when an airborne combustible dust cloud encounters an effective ignition source. The resulting pressure and temperature increase can severely injure people and damage surrounding equipment and buildings, and therefore needs to be prevented or controlled (Taveau, 2016). The article deals with the measurement of maximum explosion pressure and maximum rate of explosion pressure rise of sugar dust cloud. The measurements were carried out according to STN EN 14034-1+A1:2011 Determination of explosion characteristics of dust clouds. Part 1: Determination of the maximum explosion pressure pmax of dust clouds, the maximum rate of explosion pressure rise according to STN EN 14034-2+A1:2012 Determination of explosion characteristics of dust clouds - Part 2: Determination of the maximum rate of explosion pressure rise (dp/dt)max of dust clouds and Determination of explosion characteristics of dust clouds. Part 3: Determination of the lower explosion limit LEL of dust clouds. The sugar dust cloud in the chamber is achieved mechanically. The testing of explosions of sugar dust clouds showed that the maximum value of the pressure was reached at concentrations of 1000 g/m3 and its value is 6,89 bars.

SOLVING THE PROBLEMS OF THE SUBMERGENCE IN URBAN CONSTRUCTION SPHERE
Authors: Sologaev V. I. 
Published: March 2019

Introduction. The submergence by underground water remains one of the problems in urban construction. It is also associated with the movement of groundwater under buildings and structures. Such processes are non-stationary and their calculation is complex. The paper begins the series of researches on the methodology for solving problems of filtering groundwater while protecting against flooding in urban construction by using an operator method. Oliver Heaviside began the practical application of mathematical operators for solving engineering problems. The operator method with Laplace transformations was used. It was shown how, with the help of the Internet and Maxima program, it is easy to make inverse Laplace transformations.Methods and materials. The author considered the decision on the submergence of the city road in the presence of a dome watering under asphalt pavement in the dirt road foundation. At the same time, for filtration problems of such type, the author took into account the compaction of the engineering zone of the soil under the road. The paper showed how to solve the complex non-stationary problem of spreading the dome of the flooding under the city road. The technology of the solution is presented not only with all the mathematical details of the operator method, but also provided with new physical representations. Such an original approach, by the author’s opinion, would help better understanding of the flooding process physics in urban construction. Moreover, it would allow solving problems of protection against flooding by a new, more efficient way, taking into account the real non-stationary processes of filtration of groundwater in built-up areas.Discussion. As a result, the author presents anew statement of the operator method for solving the submergence specific problem in urban construction. First, a specific example demonstrates how to use the Internet and the license-free Maxima program. In this case, the simplest case is taken, in the form of the electricity and filtration analogy. Then the author considers the filtration spreading of the domed man-made groundwater beneath the city road. Therefore, the paper demonstrates new solutions for non-stationary filtration of groundwater in the engineering zone, which are also compared with the world practice results.Conclusions. The author presents the methodology for solving unsteady groundwater filtration problems for the submergence protection in urban construction by using the operator method and Laplace transformations. Such decisions make it possible to obtain convenient engineering formulae, by which groundwater levels, substantiate practical solutions and measures for protection against submergence in urban construction could be found. The author intends to further development of such scientific ideas and solutions for submergence protection in the built-up areas.

Cases of Damage on Heat-Treated Components – not always a Heat Treatment Problem
Authors: Sommer P. 
Published: March 2019

Abstract
When damage occurs on heat-treated components, it is initially frequently assumed that errors occurred during the heat treatment process. It could be confirmed in the course of many damage case investigations that, in principle, this might be true. However, it could also be shown that a much larger number of damage cases is caused by latent defects hidden in the component in which case the heat treatment only reveals these defects. During the heat treatment, heat and transformation stresses are unavoidable. Defects will subsequently also occur during manufacturing, after the heat treatment process, and owing to improper application conditions. Damage analysis thus not only requires a reliable measurement and examination technology but also extensive experience with materials, heat treatment procedures, and fields of application.
