Advanced Finite Element Analysis to Predict Off-Axis Crushing Behaviour of Composite Aero-Structures

Abstract:

Advanced finite element analysis (FEA) is carried out to simulate the off-axis crushing process of glass/epoxy twill/weave composite box structures. The FE results were compared to relevant experimental result and it was shown that the applied model is capable to predict the damage behaviour and energy absorption of composite box aero-structures under off-axis loading condition.
