Abstract

The work in this paper simulates the soft-body impact response of pristine and z-pin reinforced composite beams based on a novel 3-point bend type test called the 'soft body beam bend' (SBBB). Numerical results of unreinforced composite beams were compared to experimental impact tests results yielding good agreement in terms of delamination threshold velocity and global deformation behaviour. In the case of reinforced composite beams, previously validated z-pin bridging maps were applied to predict the large-scale bridging response. The numerical results predicted an enhancement to delamination suppression, raising the threshold by almost 15%. However, correlation with experiment test data was only moderately good due to the strain rate effects not being included in the model for the base composite material and z-pins.
