INELASTIC AXISYMMETRIC BUCKLING OF RING STIFFENED CYLINDRICAL SHELLS UNDER EXTERNAL PRESSURE.

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 Drucker's 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)
