摘要：
Solution of the axisymmetric thermoplasticity problem is outlined, taking account of unloading and the application of a load of opposite sign to elements of the body, under the following model concepts regarding the behavior of the material: elastic unloading, isotropic strengthening, and ideal Bauschinger effect. The difference in the calculation results is shown for a specific example. The finite-element method is used to solve the variational heat-conduction problem and the problem of determining the stress-strain state. As an example, the stress-strain state of a thick-walled cylinder is investigated.
