Basics of developing a model of deformation of elastic-plastic half-space of cast iron

Abstract

The article is devoted to the creation of a model of deformation of the elastic-plastic half-space of iron-carbon alloys, which is important for the accurate determination of the physical and mechanical properties of this material. The main objective of the study is to conduct a finite element analysis of changes in the stress-strain state of the elastic-plastic half-space of cast iron under the local dynamic action of a rigid spherical indenter. As a result of the analysis, it is planned to construct a dynamic diagram of indentation of the indenter in the coordinates "force - displacement". Successful modeling of the deformation process will significantly reduce the volume of full-scale experiments and reduce the number of samples required for testing. The ANSYS Workbench software environment was used in the modeling, in which graphical dependencies of stress-strain values were developed, describing the linear behavior of the material during deformation. Modeling was also carried out for various combinations of Poisson's ratio.
