Abstract : for analyzing the residual stress distributing state within the weld joint , and its effect on the performance of welding structure , when welding the ferrite pearlite steel with the austenite steel , this paper develops a finite element program to compute the interface stress of two or over two material . finally , this program is used to analyze the mechanical behavior of heterogenic joint 文摘:为了分析铁素体、珠光体类钢与奥氏体类钢焊接时，焊接接头处焊接残余应力的分布状态及其对焊接构件性能的影响，研制了可计算两种或两种以上材料界面应力的有限元程序，并用此程序分析了异质接头的力学行为。
