Singularities in a solution to a rotating orthotropic disk with temperature gradient

摘要

A semi-analytical solution is obtained for a rotating stress-free edge disk of constant thickness and density. In the plastic range, the Hill's quadratic orthotropic yield criterion is adopted. In the elastic range, the Hooke's law holds with thermal effects included. The analysis of singularities performed may be used for correct implementation of numerical codes and preliminary engineering design.
