The nonlinear analysis part of B2000: a first evaluation

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...

A finite element model to study the buckling behaviour of general orthotropic, midplane symmetric and elastic plates

A finite element model has been developed, which incorporates the bending-torsional coupling effect, as it occurs in general orthotropic, midplane symmetric, elastic plates in order to analyse its influence on the buckling behaviour of such plates. Some results have been compared with known exact and approximate solutions.
