Ross Group Distinguished Speaker: Shock Waves and Impacts
SHOCK WAVES AND IMPACTS - HOW TO HIT THINGS REALLY HARD

Ross Group Distinguished Speaker
The Olympic motto — Citius, Altius, Fortius, which is Latin for “Faster, Higher, Stronger” — neatly summarizes the research focus of our group. Our research areas include a mix of fluid mechanics and gas dynamics theory combined with solid mechanics and fracture dynamics. We strive to develop a deeper understanding of the response for different types of materials and structures as they are subjected to high strain rate impacts or shock wave loading. If we can better understand the failure modes of solids during highly dynamic short-duration experiments, we can then improve the dynamic response and performance of a number of applications. Some examples of specific areas of interest to us are underwater explosions near naval structures, and shock wave focusing to enhance the non-invasive treatment of kidney stones. In this talk, I will begin with a brief overview of some of our research projects after which I will introduce in more detail our shock wave dynamics research. The figure shows an example of the shock wave pattern that occurs during one of our shock focusing experiments.
Veronica Eliasson is an Associate Professor in the Structural Engineering Department at University of California San Diego. Prof. Eliasson obtained an MSc Degree in Vehicle Engineering and a PhD in Mechanics from the Royal Institute of Technology, Stockholm, Sweden. Prof. Eliasson’s research interests are multi-disciplinary and range from shock wave dynamics to fracture mechanics — all explored relying on a strong foundation of experimental mechanics coupled with different types of ultra high-speed photography techniques. Prof. Eliasson works hard to promote research experiences for a diverse group of high school students, undergraduate students and graduate students through participation in laboratory experiments.
