The present paper is devoted to problem of thermoelastoplastic deformation of hollow torus. The requisite equation of the temperature stresses theory are furnished in toroidal coordinate frame. The residual stresses in a hollow elastoplastic torus subject to non-uniform radial heating are calculated and graphically analyzed. The aproximate analytical solution of the noted problem is obtained in the framework of the generalized plane stress state approach. The stress and displacement fields are computed in the thermoelastic and plastic flow domains. The correctness and apliability of the obtained solutions for a torus of arbitrary size under conditions of axisymmetric thermal effect are discussed.
