In this paper, based on the multiplicative decomposition of the left stretch tensor an elastic-plastic modeling of isotropic hardening materials is introduced. As an application, the simple shear problem is solved and the stress components are plotted versus shear displacement for an isotropic hardening material. Also the results are compared with the results taken from the additive decomposition of the strain rate tensor, which was obtained in the other references.
