Abstract

The purpose of this study is to develop a mathematical model, which in a single scheme, and based on principles of continuum mechanics allows you to record the evolution equations of damage accumulation taking into account the geometrical and physical nonlinearities of the process. To solve this problem we propose a new approach based on the relationship of dynamic equations and the equations of material damage it.

Keywords:
