激光淬火残余应力有限元计算

A Finite Element Calculation of the Laser-Induced Hardening Residual Stress

本文将激光致热作为第二边界条件,运用热弹塑性有限元方法计算了钢柱体自冷淬火后的残余应力,计算结果与实验值接近。

In light of thermal elastie-plastic theory, this paper, by the finite element method, makes a calculation of the residual stress for a self-cooling hardening steel cylinder, with laser-induced heat as the second boundary condition. The result demonstrates that the value of calculation is close to that of the experiments.
