Elasto/visco-plastic deformation of multi-layered shells of revolution under thermal loading due to fluid
- Toyohashi Univ. of Technology (Japan). Dept. of Mechanical Engineering
An analytical method for the elasto/visco-plastic deformation of the multi-layered shells subjected to thermal loads due to fluid is developed. First, the temperature distribution through the thickness in each layer is assumed to be linear, and the temperature field in the shell is determined using the equations of heat conduction and heat transfer. Secondly, the stresses and deformations are analyzed by the thermal stress equations. The equations of equilibrium and the relationships between the strains and displacements are derived from the Sanders shell theory. For the constitutive relations, Perzyna`s equations are employed. As a numerical example, a two-layered cylindrical shell composed of mild steel and titanium subjected to locally distributed thermal loads due to fluid is analyzed. Numerical computations are carried out for three cases of the ratio of the thickness of the titanium layer to the shell thickness. It is fund from the computations that the temperature and stress distributions and the deformation vary significantly depending on the thickness ratio.
