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.
