An industrial solution to simulate post-buckling and damage of composite panels

Abstract

The SAMCEF finite-element code provides solutions for modelling and analysing post-buckling in composite structures. Post-buckling results in large transversal displacements, which means that a reliable non-linear procedure is required. Ply and interface degradation models can be used to more accurately predict the complex structural behaviour of the composite structure up to the final point of collapse. This paper presents the numerical results obtained as part of research conducted under the COCOMAT European project. Comparison with experimental results shows that SAMCEF accurately predicts the damage mechanisms, panel behaviour and collapse load.
