| Abstract: | In this paper, from an analysis of a representative volume element of shear bands of voided viscoplastic materials using the method of micromechanics, the macroscopic constitutive potential and the corresponding constitutive relations are obtained. And, taking terms of an upper bounded approach, the existence condition for a normal flow regulation is obtained for the voided viscoplastic material. |
