Abstract
The paper describes recent progress on materials modelling and numerical simulation of soft body impact on fibre reinforced composite structures. The work is based on the application of explicit finite element (FE) analysis codes to simulate composite shell structures under impact from highly deformable soft impactors such as gelatine or ice, which may flow over the structure spreading the impact load. These soft impactors are modelled here by the smooth hydrodynamic (SPH) method, in which the FE mesh is replaced by interacting particles. An improved composites ply damage mechanics model and interply delamination model are used to predict impact damage in the shell structures. Numerical simulations are compared with gelatine impact test data on glass fabric/epoxy cylinders.
