轴对称弹塑性体安定分析的边界元法

Boundary Element Method on Axisymmetric Elasto-Plasticity Body of Shakedown Analysis

本文利用几何关系、物理关系及平衡关系推导出轴对称问题弹塑性边界积分方程中四阶张量,给出计算内部点位移率、应力率及边界应力率计算公式,并对弹塑性体进行安定分析。

In this paper,the four factors in boundary integral equation of axisymmetric elasto-plasticity are obtained by the use of stain-displacement relationship,hook's law and equilibrium equation.The formulas are derived to compute the displacement rate and stress rate at internal points,and surface stress rate.The shakedown analysis is carried out for the elasto-plasticity body.
