Дискретное упрочнение как эффективный метод повышения ресурса работы элементов механизма

Abstract

In work results of of the study stress-strain state of structural elements containing the surface after the spent processing -discrete hardening, the example of a thick-walled cylinder loaded with high internal pressure. The study was carried out using the finite element method. In the consideration of the 4-th design models that take into account changes in material properties at discrete hardening and without changes to the elastic-plastic and elastic formulations, respectively. The analysis of the obtained numerical indicators components of the stress-strain state and the factor of safety for design elements.
