摘要
对准脆断情形,应用线弹性全局应力场,按照严格的内力等效(或平衡)条件,对Irwin塑性区模型进行了改进,并给出了正确的修正结果。
An improvement on Irwin plastic zone model in small yielded range is presented by means of linear elastic Stress field of overall zone, which is based on absolutely equivalent internal force. The correct modified result is obtained.
