Abstract 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.
Keywords
