Finite creep in thick-walled cylindrical shells at elevated temperatures

An analysis for creep of a material subjected to high temperatures should be based on a theory which considers both the finite strain-field as well as the anisotropicity of the material behavior.

Description
Summary:An analysis for creep of a material subjected to high temperatures should be based on a theory which considers both the finite strain-field as well as the anisotropicity of the material behavior. The creep behavior of orthotropic cylindrical shells at high pressures and temperatures is studied. The material parameters are assumed to be independent of temperature; for the sake of simplicity, Norton's law of creep is used, which does not take the frictional resistance into account. It is found that the temperature variation has a significant effect on the strain and strain-rate, an effect which is most prominently manifested at longer time periods or higher strains, particularly for anisotropic materials.
