Abstract: The feasibility of a viscoplastic model incorporating two back stresses and a drag strength is investigated for performing nonlinear finite element analyses of structural engineering problems. The ...

Abstract: The problem of primary creep of an orthotropic thick-walled spherical shell under internal pressure has been analyzed in this paper. The creep stresses and strains have been calculated using a ...

Abstract: The stress and strain-rate distributions in the wall of a hollow thick-walled circular cylinder, rotating about its own axis with a constant angular speed, have been obtained using Norton’s law ...
