A step algorithm (in terms of additional loadings) of the initial deformation method is suggested for solving nonisothermal thermoplasticity problems by the method of finite elements. The algorithm permits the problem of finding the stress-strained state of bodies to be solved using the nonisothermal isotropic theory of plastic flow for an arbitrary combination of force and temperature loadings with consideration of the mechanical constants-temperature dependences of the material. The described peculiarities in the computational algorithm organization contribute to an appreciable reduction in the computer time when solving particular problems. The algorithm of concern served as a basis for constructing a computational 'Thermoplasticity' complex for solution of two-dimensional (plane and axisymmetric) problems.
