Abstract

The methods of mathematical modeling of stress-strain state of metal during rolling were analyzed. Based on the received bonds mathematical models for determining the local characteristics of the stress-strain state of metal in the zone of plastic forming were established. The data on the size is somewhat smaller than the data obtained on the basis of numerical recurrent solutions of finite-difference form of the equilibrium condition. It was found that the degree of mismatch of the energy and force approaches was less than 3%.
