Strain Factor Ratio Criterion for Crack Extension in Anisotropic Plates
Publication: Journal of Engineering Mechanics
Volume 125, Issue 1
Abstract
Due to the fact that certain brittle extensions of cracks in anisotropic materials are caused by the surpassing of the limit strain by the actual strain produced by the load, a strain criterion (re-criterion) is proposed in this paper. Parameter studies of the re-criterion for the extension direction and initiating load are carried out. Comparisons between the re-criterion, some stress criteria, and the independent experimental results are made. It is shown that the re-criterion can predict quite accurately both the extension direction and the initiating load. The re-criterion is more general than the stress factor ratio criterion in that it takes into account the influence of Poisson's ratio in predicting the crack extension direction and the initiating load. The re-criterion can be reduced to the stress factor ratio criterion in certain cases. The prediction of crack extension direction and initiating load can be quite different using different criteria.
