Predicting low-velocity impact damage on a stiffened composite panel

The high-fidelity, physically-based damage models, developed in this paper, advanced the predictive capabilities of numerical simulation in capturing the complex failure mechanisms in composite aerostructures. The correlation with independently published experimental results was superior to what had been published in the literature up to that point. This work laid the foundation for current research, sponsored by the Cooperative Research Centre for Advanced Composite Structures in Australia (contact Prof M. Scott (CEO)) , for the development of a computational capability for modelling the crushing of composites structures to improve the crashworthiness design of helicopter structures.
