粘塑性有限元分析隐式积分方案公式的统一形式

A Unified Expression of the Fully Implicit Time Marching Scheme in the Visco-plastic Analysis of Finite Element

本文推导了粘塑性有限元分析中隐式积分格式的统一表达式,它包括特雷斯卡(Tresca)、米赛斯(Von-Mises)、莫尔-库仑(Mohr-Coulomb)、德鲁克-普拉格(Drueker-Prager)和监凯维奇(Zienkiewicz)五种屈服准则。并给出一个算例以说明这种公式的效果。

In this paper, a unified expression of the fully implicit time marching scheme in the visco-plastic analysis of finite element is derived. It incorporates five yield crite-rions of Tresca, Von Mises, Mohr-Coulomb, Drucker-Prager, and Zienkiewicz. A numerical example is presented to illustrate the capabilities of this expression.
