摘要
在焊接过程中产生的动态应力应变及随后形成的残余应力,是导致焊接裂纹和接头性能下降的重要因素。因此,焊接残余应力一直是人们关注的热点问题。结合焊接残余应力的研究方法与手段,介绍近年来国内外关于焊接残余应力的研究现状与发展。
The dynamic stress-strain and welding residual stress during welding are the significant factors which lead to welded cracking and debasement of the joint properties.Therefore,the welding residual stresses are still very important problems.By means of the welding residual stress,present status and developments of numerical simulation about welding residual stress are introduced recently.
