Article 0 Reads 0 Citations Finite element analysis of displacements state for circular plates C Popa, F V Anghelina, V Despa Published: 29 November 2018
IOP Conference Series: Materials Science and Engineering, doi: 10.1088/1757-899x/444/6/062020
DOI See at publisher website ABS Show/hide abstract
The paper analyzes the states of displacements that are born in a smooth circular plate, compared with a circular plate with radial ribs placed on one side, under the action of a pressure. The study is done using the finite element method. Thus, in order to resist the same pressure, it will be deduced that the ribbed plate will have a thickness more half smaller compared to the smooth plate.

The paper analyzes the states of stresses that are born in a circular plate with radial ribs placed on one side, under the action of different pressures. The study is done using the finite element method and the experimental method. For this purpose, the value of the stresses for the plate is determined, in case of different solicitations. From the analyzed study we can see the close results that have been obtained.

The structural transformations occurring at tempering for some high-speed steels are a subject of research for which have been dedicated numerous studies. More complex compositions of the high-speed steels were direct consequence of the complexity of structural transformations which occur during heat treatment. On the other hand, current tendency in energy requires maximum efficiency and rational use of heating sources used in industry. Thus, only a precise knowledge of the kinetics of transformations occurring at tempering can be a basis for optimizing this treatment. Although cobalt is used for a long time as an alloying element, though relatively recently it was considered important to the properties of rapid steel. These circumstances, combined with the lack of quantitative information on the kinetics transformation at tempering operation treatment for some steel has led to this paper. The thickness of the studied samples is 5 mm and was taken from the annealed steel bars. These samples were subjected to hardening and tempering treatment in salts bath. Heating for hardening was performed in two steps, at 5500C and 8300C. Austenitizing was done at 12000C, during 120 seconds. The cooling was done up to 5300C in salts bath, with a keeping of 15 seconds, and then air cooling was done. On these samples were carried out, HRC Rockwell hardness measurements, and X-ray diffraction analysis.
