Limiting equilibrium state of an anisotropic plate with a partially healed crack

The plane problems of the theory of elasticity of anisotropic bodies with partially injection-healed technologies of the Mode I and Mode II crack-life defects were solved. Using the appropriate (for the loading mode of bodies) models of the Winkler basis regarding the action of the filler on the areas of the crack surface, the problems are reduced to solving singular integro-differential equations with respect to the jump functions of normal and shear displacements of the points of the crack edges. The numerical solutions of these equations were obtained by the quadrature method under the conditions of a generalized plane stress state of the body. The influence of the volume of crack filling with the injection material and the anisotropy of the plate materials on the change in the stress intensity factors and critical loads was determined.
