In this paper, the residual welding stresses in a low carbon steel girth butt welded pipe are calculated with a nonlinear finite element code ADINA.
本文利用ADINA非线性分析有限元程序，对低碳钢管道环焊缝接头焊接残余应力进行计算。
But this method is used to determine welding residual stresses in many cases where the stress peaks are often near the material's yield strength.
但是在许多情况下，钻孔法是用于测量焊接残余应力，而该应力峰值往往接近材料的屈服极限。
The pipe with original welding residual stresses is analyzed under different conditions of PWHT.
