butt welded

基本解釋

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非線性分析有限元程序，對低碳鋼管道環(huán)焊縫接頭焊接殘余應力進行計算。
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.
計算預測值與實測值基本一致，表明有限元法能夠經濟而有效地預測管道環(huán)焊縫接頭的焊接殘余應力。
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.
根據試驗測定的焊縫各區(qū)沖擊韌性、斷裂韌性、疲勞裂紋擴展速率和疲勞裂紋擴展門檻值，對焊縫力學性能作出綜合評價。
