Multilayered cylindrical panels with interface diffusion and sliding under thermomechanical loads

We investigate the time-dependent deformations of multilayered isotropic elastic cylindrical panels with interfacial diffusion and rate-dependent sliding under thermomechanical loads. The state-space approach is found to be extremely effective for the analysis of a cylindrical panel composed of an arbitrary number of layers. We show that when a particular condition is met, the thermal loading will not induce any thermal stresses in the cylindrical panel. To demonstrate our results, we present the evolving displacements and stresses in a three-layered panel induced by sinusoidal temperature variation and normal traction applied to its upper surface. In addition, we present all 198 relaxation times corresponding to a 100-layered panel.
