Effective local stress intensity factor criterion for prediction of crack growth trajectory under mixed mode fracture conditions
Theoretical and Applied Fracture Mechanics(2016)
摘要
•The proposed criterion considers material properties in crack growth direction.•A material-dependent effective local SIF is defined as a main fracture parameter.•The ratios of shear strength to tensile one in various materials are considered.•The predicted results are in a good agreement with the experimental ones.
