Journal ArticleDOI
Mixed mode crack propagation in homogeneous anisotropic solids
TL;DR: In this paper, the authors extended the maximum circumferential tensile stress theory to anisotropic solids, and formulated the criteria in terms of the maximization of the ratio of the Maximum Circular Tensile Stress (MCTS) over the material critical tensile strength.
Journal ArticleDOI
A fracture mechanics based seismic analysis of concrete gravity dams using discrete cracks
TL;DR: In this article, new models for the efficient simulation of discrete crack closure, and fracture mechanics based model for crack propagation, both under transient dynamic conditions, were developed and integrated into an interactive graphics program which was used to analyse Koyna dam.
Journal ArticleDOI
Criteria for brittle fracture in compression
TL;DR: In this article, a crack resistance function is defined based on experimental data and then combined with an average state of stress in front of the cracktip to formulate a crack driver function, analogous to the safety factor.
Journal ArticleDOI
Prediction of crack propagation in anisotropic solids
Ye Zhiming,Mohamed L. Ayari +1 more
TL;DR: In this paper, the authors extended the minimum strain energy density theory for crack growth in isotropic solids to the anisotropic case and formulated a criterion for predicting the direction and onset of crack growth.
Journal ArticleDOI
Maximum strain theory for mixed mode crack propagation in anisotropic solids
Mohamed L. Ayari,Zhiming Ye +1 more
TL;DR: In this paper, the authors derived the maximum strain theory for mixed mode crack propagation in anisotropic solids based on the Sib and Liebowitz's solution of the near crack tip stress distribution and discussed the macroscopic strength via a maximum circumferential strain factor.
