Buckling and Post-Buckling Behaviour of Impacted Glass Reinforced Composite Plates under Compression after Impact Tests

Abstract

The present work deals with the Compression After Impact numerical simulations on low velocity impacted glass fibre reinforced composite plates configurations characterised by three different stacking sequences. The damaged numerical FEM models, deriving from impact explicit analyses, have been used as an input to perform explicit analyses simulating the compressive test. The drop, in terms of compressive residual strength, is analysed and discussed. Considerations on the buckling and post-buckling behaviour of these plates under compression are then introduced.
