Riks, E. (author), Merazzi, S. (author), de Boer, A. (author)In many practical problems of plate and shell buckling, the pre-buckling state is linear and can be obtained from the linearized equations of elasticity. The computation of the buckling load and mode in such cases correponds to a linear eigenvalue problem that can easily be formulated and implemented in a finite element code. This report...report 1988

de Boer, A. (author), Riks, E. (author)In this report a description is given of the nonlinear package of B2000. The set-up of the continuation procedure which controls the nonlinear calculations is explained. At some points the existing continuation procedure was modified to enhance its performance. The nonlinear package contains a nonlinear rod element and a nonlinear thick shell...report 1988
