摘要
本文简要介绍了热弹塑性断裂分析有限元软件系统TEPFA的主要功能、使用技术和基本结构。该系统有如下主要功能:(1)采用自动优化固有应变法模拟焊接残余应力;(2)热/残余应力存在时的弹塑性断裂分析;(3)采用节点力释放技术模拟稳态裂纹的扩展。
This paper introduces briefly the related functions, techniques and structure in a finite elememt program system for thermal-elastic-plastic fracture analysis. This software includes: (1) estimation of welding residual stresses by using simulated inherent strains; (2) elastic-plastic fracture analysis in the presence of thermal and residual stresses; (3) simulating stable crack growth by using the technique of releasing the crack tip no de forces.
