摘要：
Modification of previously developed mathematical models and software for finite-element simulation of deformation of stainless steel structures operating under quasi-static thermal and neutron irradiation conditions is performed. The models of plasticity, radiation swelling, thermal and irradiation creep proposed in the work allow using the damaging irradiation dose and its intensity as neutron irradiation parameters. The list of material constants and functions of the material of the developed deformation models is formulated. On the basis of the functional dependences generalizing the experimental data on the regularities of deformation of stainless steel 08Kh18N10T under thermal and radiation effects, the models of plasticity, swelling and irradiation creep are verified.
