prediction of crack propagation path under general mixed mode loading
What is it about?
To predict the crack propagation trajectory under general mixed mode loading, a novel criterion has been developed. For this purpose, the material-dependent effective stress proposed in the maximum effective stress criterion based on involving all effective components in crack extension under mixed mode I/II, has been developed for mixed mode I/II/III. The effects of the ratio of fracture toughness in mode III to that of mode I (KIIIC/KIC) on the crack growth have been considered by using a new material parameter. The predicted results of developed criterion in different mixed mode conditions show good agreement with the available experimental ones.
