Limiting Equilibrium of a Piecewise-Homogeneous Body with Shear Cracks at the Corner Point of the Interface.

The Wiener–Hopf method is used to find the exact analytical solution of the problem of fracture mechanics for a piecewise-homogeneous isotropic elastic body with shear cracks at the corner point of the interface. The behavior of the stress concentration at the crack tip is established. The growth condition for the cracks is determined and the stability of their equilibrium is analyzed. [ABSTRACT FROM AUTHOR]
