摘要
本文通过对粘塑性材料剪切带中含孔洞的代表体元的细观力学分析,得到了剪切带的宏观本构势和本构关系。采用上限方法,给出了多孔粘塑性材料正交流动法则存在的条件。
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.
