TIME-DEPENDENT STRESS-LIMITED MECHANICAL MODELS OF ELASTO-PLASTIC PROCESSES

Abstract

In generall, the mechanical models are described by different type of differential equations. In the approach presented here the unconstrained optimization problem that derives from the boundary problem is decomposed into a pair of constrained optimization problems. In this paper the presented models concerning the stress-limited elasto-plastic state change include the theoretical results of the earlier studies. The theoretical results are illustrated by some numerical examples.
