Shock Wave Interaction and Impact

Shock Wave Interaction and Impact

Highly dynamic and extreme conditions occur in both fluids and solids. It can be particularly challenging to predict - using analytical or numerical tools - the dynamic response of materials and structures at very high strain rates. To help understand these dynamic phenomena, the Shock Wave and Impact Laboratory performs experimental work on both fluids and solids, often with some type of coupling between the two media. In particular, we focus on non-invasive visualization techniques that can help us to ‘see things’ that are invisible to the naked eye. Thus, the newest equipment we have recently acquired is an ultra high-speed camera that can capture photographs with frame rates up to ten million frames per second. This setup allows us to study a range of diverse phenomena such as shock wave interaction between multiple synchronized shock waves (sponsored by AFRL), mechanical and biological response during traumatic brain injury, and dynamic fracture initiation and propagation of polymeric materials (sponsored by ONR). With the knowledge gained through this work, we aim to in the future help to create structures, devices, and vehicles that are stronger, lighter, faster and with improved properties.
