Numerical Study of Inelastic Deformation of Structurally Inhomogeneous Bodies of Revolution Taking Into Account Thermomechanical Loading and Radiation Exsposure

The problem is stated and the algorithm for solving the problems of thermoradiation plasticity for axisymmetric bodies made of isotropic and orthotropic materials, whose properties depend on the temperature and the value of the radiation dose, is described. The modified equations of thermoradiation plasticity are proposed to describe the deformation processes of isotropic materials along the trajectories of small curvature. The dependences between the second invariants of stress and strain deviators obtained experimentally using samples are used for their linearization. The equations of the theory of elasticity are used to describe the deformation of orthotropic materials. The radiation swelling of materials is taken into account. The effect of mechanical and thermoradiation loading on the results of calculating the stress-strain state of shells of various shapes is studied. The numerical results are presented in the form of curves.
