Stress intensity factor for multiple inclined or curved cracks problem in circular positions in plane elasticity

The problems of multiple inclined or curved cracks in circular positions is treated by using the hypersingular integral equation method. The cracks center are placed at the edge of a virtual circle with radius R. The first crack is fixed on the x‐axis while the second crack is located on the boundar...
