A DOUBLE PERIODIC SYSTEM OF RECTILINEAR CRACKS WITH CONNECTIONS BETWEEN THE EDGES

The problem of tension and shear of a thin isotropic plate weakened by a doubly periodic system of rectilinear cracks with end zones is considered. General representations of solutions are constructed that describes a class of problems with a doubly periodic stress distribution outside cracks. The main singular integral equation of the problem is reduced to an infinite system of algebraic equations. Due to the unknown size of the end zone, the system of equations turned out to be non-linear even with a linear bond deformation law.
