焊接接头J积分断裂参量的有限元数值分析
Numerical Finite Element Analysis of J-integral Fracture Parameters for Welded Joints
【摘要】 对中心裂纹和单边裂纹板远场均匀拉伸条件下的焊接接头试件做了有限元计算和分析 ,得出了一些适合不同焊接接头的J积分测试方法和计算公式。
【Abstract】 The J integral fracture parameters of welded joint specimens were calculated and analyzed by far field uniform tension tests of plates with single dege and middle cracks. Testing methods of J integral and expressions for different welded joints were gained.
