| Abstract: | The stress and deformation of the structrue of a thickwalled viscoelastic cylinder with elastic metallic shell were discussed when its internal pressure was increasing.Viscoelastic constitutive expression made use of Swanson nonlinear constitutive equation,The basic equations for solving stress and deformation were given.And the stress and deformation were influenced by softening function,nonlinear term and inertia force.It supplies the foundation to next numerical calculation. |
