A method for numerical analysis of the thermoelastoplastic axisymmetric stress–strain state of thin isotropic shells undergoing mechanical loading and radiation exposure is outlined. The modified constitutive equations of thermoplasticity describing inelastic deformation along small-curvature paths are employed. The thermoelastoplastic state of a shell in the form of a spherical segment is analyzed numerically with allowance for the effect of radiation.
