| Abstract | In this work, impact simulations using both meshfree Smoothed Particle Hydrodynamics (SPH) and combined FEM/SPH Method were carried out for a sandwich composite panel with carbon fibre fabric/epoxy face skins and polyetherimide (PEI) foam core. A numerical model was developed using the dynamic explicit finite element (FE) structure analysis program PAM-CRASH. The carbon fibre/epoxy facings were modelled with standard layered shell elements, whilst SPH particles were positioned for the PEI core. We demonstrate the efficiency and the advantages of pure meshfree SPH and combined FEM/SPH Method by comparing the core deformation modes and impact force pulses measured in the experiments to predict structural impact response. |
