NUMERICAL MODELING AND DETERMINATION OF THE STRESS-STRAIN STATE OF RAILWAY WHEELS WITH THE PRESENCE OF SUBSURFACE PHYSICAL TYPE STRESS CONCENTRATORS
Problem statement. The problem of establishing the stress-strain state of carriage wheels with the presence of subsurface inclusions is considered. Purpose. The purpose of this article is to build a methodology to establish dependence between the parameters of subsurface inclusions and the contact strength of railway wheels. Methodology. Based on modern models of the mechanics of a deforming solid of non-local (gradient) media, approaches to assessing the strength of structures and methods of mathematical modeling, the spatial distribution of the field of displace
