Modelling of partial closing of cracks in the environment with emptiness

On the basis of methods thermoelasticity the mathematical description of model of partial closing of cracks in heat-generating the isotropic massif weakened doubly periodic by system of cylindrical channels of round cross-section is lead. It is considered, that in process of increase of intensity of a heat release in a massif there is a destruction of a material. Definition of unknown contact stress and the sizes of zones of contact is reduced to the solution singular the integrated equation.
