Abstrac&-The minimum strain energy density theory, originally developed for crack growth in isotropic solids, is extended to the anisotropic case. The criterion for predicting the direction and onset of crack growth is reformulated through minimization of the ratio of the strain energy density (writ

The maximum circumferential tensile stress theory, originally developed for isotropic solids, is extended to an anisotropic one. A two parameter fracture toughness characterization is assumed, and a simplifying relationship among them postulated. The criteria is reformulated in terms of the maximiza
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 com
