摘要：

The maximum strain theory for mixed mode crack propagation in anisotropic solids is derived. Based on the Sih and Liebowitz's solution of the near crack tip stress distribution in anisotropic solids, the macroscopic strength is discussed via a maximum circumferential strain factor. The theory is compared with the maximum circumferential stress theory for anisotropic solids of Saouma and Ayari and the minimum strain energy density theory for anisotropic solids, proposed recently by Ye and Ayari. It is found that all these theories have similar trends in predicting the onset of crack growth and direction of crack propagation. The maximum strain theory is also found to be the most conservative in comparison with the other theories.
