Thermal Stress Solution for Multilayered Composite Cylinders

摘要

An elastic thermal stress solution is presented for a multilayered compositecylinder subjected to a radial temperature field. The solution assumes each layer to be at a uniform temperature, therefore, many layers are required to model regions with large gradients in temperature. Previously developed closed-form solutions for a monolayered cylinder subjected to a uniform temperature change and loadings of internal and external pressures are used to construct the multilayered solution. Results produced by the theoretical solution have been compared to those generated from a finite element analysis with excellent agreement. Finally, by combining a previously developed multilayered stress solution for loadings of internal pressure, external pressure, and axial force with the plane-strain thermal stress solution of this report, the multilayered thermal stress solution for generalized plane-strain boundary conditions is shown to be easily obtained....
