Modeling the Reconditioning of Worn-Out Hollow Cylindrical Machine Parts by Thermomechanical Deformation

A thermomechanical model of reconditioning worn-out hollow cylindrical machine parts by thermoplastic compression is developed. The scheme proposed takes into account the main stages and features of the process, in particular, the contact interaction between the cylinder and a rigid punch under compression. The ultimate and residual stresses and process parameters are determined
