Stress State of a Thick-Walled Cylindrical Shell under the Combined Action of Radiation and Temperature Field

Abstract

There is a solution of the problem of stress-strain state determining in a concrete thick-walled tube, when the temperature field and the neutron fluence at the inner face are set. The mutual action of the specified factors is identified in this axisymmetric problem, as well as influence of inhomogeneity of shell materials, which is due to radiation and heat impact. The problem reduces to a differential equation with variable coefficients. The allowance for the mutual action of the specified factors and the variable Young’s module lets to arrive to a more accurate solution.
