摘要
本文对平面应力和平面应变状态下不同组配焊接接头的失效评定曲线进行了有限元计算，并对焊接接头失效评定曲线的工程估算法进行了一些初步的研究。
Based upon the EPRI/GE J-estimation and the CEGB/R/H/R6 approachs, the failure assessment curve of R6 route was studied by finite element method. By taking a simple engineering assumptions and synthesizing the relevant data, the influence of strength mis-matching on the mis-matched weldment was discussed and an approximate method of engineering treatment models of calculating the failure assessment curve of weldment was given. Comparing of the result, the data which calculated by approximate methods are in coincidence with the result derived by finite element method.
