Thermoelasticity of orthotropic shells under the action of a moving concentrated heat source

Abstract

We solve the problem of thermoelasticity for thin orthotropic shells of nonnegative curvature under the action of a concentrated heat source that moves over the surface of the shell. A linear temperature distribution over the thickness of the shell and convective heat exchange from its lateral surfaces by the Newton law are established. Using Fourier and Laplace integral transformations, we obtain a solution in the analytic form. The influences of the thermomechanical properties of the material and parameters of heat exchange with the surrounding medium on the stress-strain state of the shell are investigated.
