通过与现有的周向表面裂纹管道J积分解对比 ,证明了本文开发的有限元程序计算所得J积分解是准确的。在此基础上 ,本文通过有限元计算提供了周向外表面裂纹管道在拉伸、弯曲以及拉弯联合载荷作用下的J积分解 ,作为对EPRI延性断裂手册的补充 ,为含缺陷压力管道断裂评定提供了大量J积分解。 By comparing with the J integral solution of the existing circumferential cracked pipe, it is proved that the J-integral solution obtained by the finite element program developed in this paper is accurate. On this basis, this paper provides the J-integral solution of the cracked pipe with circumferential outer surface under tension, bending and combined bending and bending loads by means of finite element calculation. As a supplement to the EPRI ductile fracture manual, The rating provided a large number of J-integral solutions.
