Design of Advanced Composite Materials for High-Performance Vehicles: Quasi three-dimensional woven composites which improve the delamination resistance and energy absorption capabilities, while maintaining adequate in-plane properties of structures.

Dynamic Test Facility for Laboratory Simulations: A laboratory-based ‘shock tube’ is available for physical simulation of high-energy impacts and crash loads.

Numerical modeling techniques are being designed to simulate the response of composite vehicles subjected to blast, impact, and crash loadings. The approach is based on a meshless peridynamic scheme incorporating progressive damage processes, solid-solid contact and solid-fluid interaction mechanisms.
