Abstract
The calculation of the structural elements and mechanisms strength is one of the most important stages while their developing. Initial deformations are almost always available in the structural elements and machine parts. Stresses being initiated can cause their fracture and accelerate some phase transitions, corrosion in particular. To raise the accuracy of calculations the initial deformations must be taken into account. In the article the solution of the axesymmetric contact problem of the ring punch pressure on the preliminary stressed thick plate, being modeled by the elastic semi-space were obtained. The effect of the punch shape and the nature of the initial deformations on the distribution of the contact stresses under the punch was
analysed.
