Considered concrete cylindrical body in axisymmetric formulation (plane strain condition), exposure to radiation and temperature effects. The influence of physical fields on the mechanical characteristics of the material of the body individually or in the aggregate. It is shown that the stress-strain state of the cylinder, under the joint account of the different physical fields, is very different from the stress-strain state, obtained by summing the individual results of the calculation of each factor separately, that is, the superposition principle is not respected.

Keywords: temperature field, radiation, stress-strain state of the cylinder, the change of physical and mechanical parameters of the body
