摘要
本文应用参变量变分方法处理Perzyna粘塑性问题,将原问题化为求解带约束条件的二次规划问题,文中具体讨论了用于该问题的有限单元形式及具体实施过程.
Perzyna model in viscoplasticity has been studied by the parametric variational principle, which could be transformed into solving the parametric quadratic programming problem. The FEM form of this problem and its implementation have also been discussed in the paper.
