The Optimal Control Variational Principle and Finite Elements Analysis for Viscoplastic Dynamics
-
摘要: 本文运用最优控制变分理论,对Perzyna型粘塑性体,提出了粘塑性动力问题的参数变分原理,并给出了相应的动力有限元方程和参数二次解法.Abstract: This paper presents the optimal control variational principle for Perzyna model which is one of the main constitutive relation of viscoplasticity in dynamics. And it could also be transformed to solve the parametric quadratic programming problem.The FEM form of this problem and its implementation have also been discussed in the paper.
