在此基础上，对复合材料的拉伸应力-应变曲线进行了考虑热残余应力的有限元预测。
Based on the analyzed results, the tensile stress-strain curves of the composites were predicted with or without the residual stresses considered.
对存在热残余应力时复合材料的应力—应变曲线进行了模拟；
The tensile stress -strain curves of composites were also simulated.
应力应变测试表明：焊缝与熔合区是残余应力比较集中的地方，热影响区的残余应力比较小。
Stress-strain tests show that: the weld residual stress and the fusion zone is relatively concentrated, the residual stress of the heat affected zone is relatively small.
