Thermo Elasto-Plastic Analysis of Rotating Axisymmetrical BodiesUsing Modified Von-Mises Yield Criterion

In the present work, the behavior of thick-walled cylinder of elasto-plastic material (polymeric material) has been studied analytically. The study is based on modified Von-Mises yield criterion (for non metallic material). The equations of stress distribution are obtained for the cylinder under gen...
