摘 要:文中建议一个岩石的复合型等效周向应变准则,这一准则与作者的实验结果接近。本文还建议了两个复合型初始断裂经验准则。
Abstract: In the present study,an equivalent circumferential strain criterion of mixed-mode fracture initiation in rock is suggested.This criterion is in agreement with authors’ xperimental data.Two experimental criteria are also suggested in this paper.
