Weight functions and stress intensity factors for two unequal-length collinear cracks in an infinite sheet
Engineering Fracture Mechanics(2019)
摘要
•Highly accurate weight functions for two collinear cracks are presented.•Highly accurate SIFs and CODs can be obtained by using the weight functions.•The weight functions is efficient for the analysis of structure with multiple site damage.
