Abstract:

The effects of prebuckling deformation caused by the ring constraints on the inelastic stability of ring stiffened cylindrical shells under external-pressure and deformed axi-symmetrically are studied. By Druckers postulate of positive work in plastic deformation, a modified incremental theory of plasticity on the stress-strain relationships expressed in terms of Kirchhoff stress and Green strain rates is developed. Furthermore, a variational principle in Lagrangian descriptions and for quasi-static problems of finite plasticity is developed and employed to solve the problem. Author
