【 摘 要 】

The problem of mechanics of fracture about nucleation of the cracks which are starting with contours of circular apertures punched isotropic body at transverse shear is considered. The solution of a problem on balance of the punched body at transverse shear with prefracture zones is reduced to the solution of two infinite algebraic systems and two nonlinear singular the integro-differential equations with a nucleus such as Cauchy. From the solution of these equations are tractions in zones of nucleation of cracks. The condition for the appearance of a crack is formulated, taking account of the criterion of the limit traction of the bonds in the material.
