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。
The mechanical properties of the butt welded joints have been evaluated according to the impulsive and fracture toughness as well as the rate and threshold values of fatigue crack propagation.
The present invention is the production process of steel flange blank, especially of flat flange, butt welded flange and prestressed pipe pile end plate flange.
一种钢法兰毛坯加工工艺,尤其是一种平法兰、对焊法兰、预应力管桩端板法兰毛坯加工工艺。
This kind of nanostructured surface layer with compressive stress could significantly increase the fatigue strength of butt welded joint.
