Results of the computation under the same welding temperature field show that the longitudinal residual stresses in the weld are as high as the yield strength of the plate in the strength and TEC evenmatched joints, lower than the yield strength of the plate in the strength evenmatched and TEC undermatched joints. It also has something to do with the strain hardening exponent of the weld metal in the strength evenmatched and TEC overmatched joints.

计算结果表明：等强等胀匹配的焊缝区纵向残余拉应力水平高达母材的屈服强度，等强低胀匹配的焊缝区纵向残余应力水平低于母材屈服强度，等强高胀匹配的焊缝区纵向残余应力水平还与焊缝应变硬化指数有关。

Thirdly, with the modified Gurson model of the MARC finite element method soft, the damage behave of the welded joint was simulated. It was found that in the undermatched welded joint, the damage mainly happened in the soft weld line and with the decrease of the weld line抯 width, the damage抯 development was faster. As for the overmatched welded joint, the results showed that the damage mainly happened in the soft base metal and with the increase of the weld line抯 width, the damage抯 development was faster. While the width of the weld line was narrower than three millimeters, the high strength weld line could improve the anti-damage capability of the overmatched welded joint.

通过计算发现在低匹配的焊接接头中，损伤主要发生在低强度的焊缝中，并且焊缝宽度越小，焊接接头的损伤就越严重；而在高匹配的焊接接头中，损伤主要发生在紧临焊缝的强度较低的母材上，随高强度焊缝宽度的增加，焊接接头的损伤发展程度加剧，当焊缝宽度小于3mm时，高强度焊缝的加入对焊接接头能起一个强化的作用，提高了焊接接头的抗损伤能力。
