本文采用改进后的固有应变法对对接焊管接头残余应力计测进行了理论分析,确定了测量方案,研究果结表明对于可处理成轴对称问题的对接焊管残余应力问题只需不太多的测量值就能获得残余应力全场。本文就一个对接焊钢管试件进行了实验,实验计测结果同其它文献较为一致。它显示了应用改进后的固有应变理论决定对接焊钢管残余场的有效性。 In this paper, the improved method of inherent strain method was used to measure the residual stress of butt-welded pipe joints, and the measurement scheme was confirmed. The results of the study showed that only a small amount of measurement is needed for the residual stress problem of the butt welded pipe that can be processed into axisymmetric problems The value of residual stress can get the audience. In this paper, a butt-welded steel pipe specimens were tested, the experimental measurement results are more consistent with other literature. It shows the validity of the residual field of butt-welded steel pipe by using the modified theory of inherent strain.
