Elasto-plastic constitutive relation under general loading law<br /> in strain space<br />
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 1
Abstract
In this paper, the elasto-plastic model of general loading law is generalized from one dimensional stress and strain space into multi-dimensional stress and strain space. The method of derivation of elasto-plastic constitutive relation is established under general loading law in stress space and strain space. By using this method, the expressions of the heat-elasto-plastic constitutive relation are derived from stress loading functions and strain loading functions. Theory and practice show that this method applies to perfect plasticity material, isotropic hardening material and kinematic hardening material.
