Analysis of Elastoplastic Behavior Model of Antifriction Polymers

Abstract:

The analysis of properties of the antifriction materials suitable for use as materials of a surface of sliding of contact nodes was made and the elastoplastic model for the description of their behavior has been chosen in the work. The general mathematical statement of the problem of friction contact interaction of two elastic bodies through an elastoplastic antifriction layer taking into account all types of a contact state has been made. Check of mathematical statement within numerical realization of an experiment on uniaxial compression of a sample by press plates taking into account friction on the interfaced surfaces has been executed. Assessment of convergence of the numerical solution of the task of contact parameters depending on a number of nodal unknowns has been made, optimum finite element decomposition of the model has been chosen. It has been established that the numerical solution gives a good quantitative capability to results of a natural experiment. It has been established that all paths of deformation have small curvature in all considered points of the polymeric cylindrical sample.
