计算裂缝张开面积和裂缝张开体积的几个公式

SOME FORMULAS FOR CALCULATING CRACK OPENING AREA AND CRACK OPENING VOLUME

以显式给出计算有限域中裂缝的张开面积和张开体积的有代表性的算例公式。指出文献 [1 ]以积分形式给出的解答有欠缺 ,而且并不完善 ,本文给出相应的补正。本文的工作也是对应力强度因子手册中只有无限域中公式的补充。

Explicit formulas for calculating COA and COV in finite domains are given for representative problems. It is pointed out that the solution given in an integral form [1] was inadequate and incomplete, the corrections are given in this paper accordingly. This work also supplements the SIF handbook where only infinite domain solutions are available.
