Materials and Structures under Extreme Conditions
This program portfolio covers work in fundamental and applied research areas. The fundamental research is focused on understanding the scientific phenomena associated with extreme loading events on materials from blast to shockwave and from high velocity to hyper velocity impact. Special emphasis is placed on developing novel experiments, diagnostics, and characterizations to formulate constitutive models, and develop multi-scale computational methods to understand the material behavior of different materials at relevant time scales. There is a specific interest in understanding the shock physics of polymers, glassy materials, and other materials. Other interest areas include the mechanics of mitigating blast effects on ship structures, vehicles, and helmets associated with the use of novel coatings, meta-materials, and foams, as well as fluid/structure interaction related to slamming sea loads.
The applied research is directed at identifying computational codes for modeling & simulation (M&S) for design of protection systems. This area seeks new opportunities for protection in extreme conditions (blast, ballistic impact and shock mitigation) technology solution; e.g., integrating polymer coatings with steel, aluminum or composites to enhance their properties and functionalities (such as, integrating polymers with advanced combat helmet architectures to mitigate traumatic brain injury exposure). Examples of applied research projects include testing in extreme conditions (e.g., hyper velocity impact, and laser effects), including development of diagnostics and computational codes of materials and structures under extreme conditions.
