butt welded

基本解释

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。
It is show that finite element method (FEM) can be capable of predicting the welding residual stresses in girth - butt welded pipes economically and effectively.
计算预测值与实测值基本一致，表明有限元法能够经济而有效地预测管道环焊缝接头的焊接残余应力。
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.
根据试验测定的焊缝各区冲击韧性、断裂韧性、疲劳裂纹扩展速率和疲劳裂纹扩展门槛值，对焊缝力学性能作出综合评价。
