Macrocrack interaction with arched microcracks under antiplane shear

Simulation of physical processes

The paper focuses on the semi-infinite III-mode crack interaction with a structure of arched cracks that arranged in the arc centered at the main crack vertex. Through the use of a generalized integral Mellin transform the problem has been reduced to a singular integral equation with a closed-form exact solution. The relationship between the stress intensity factor and the microstructure parameters has been studied.
