Short Course Overview

ABSTRACT

This two-day short course is intended as an introduction to blast physics, loading, and target response for researchers investigating blast injury phenomena, developing diagnostics or treatments/therapies, as well as biomechanical engineers and material scientists developing protective technologies.  Key aspects of theory, modelling, and experimentation will be covered, and important terminology regarding shock processes and gas-dynamic flow conditions will be explained. Emphasis will be placed on understanding the fundamental principles of blast to a sufficient extent that experiments and models can be properly staged and interpreted.

FORMAT

The format for the course will be informal with as much allowance for discussion as can be afforded through the sessions. Live demonstrations will be performed using the advanced blast simulator (ABS) at Iowa State University. See the following link to learn more about the ABS: https://www.me.iastate.edu/sbentil/2024/05/24/advanced-blast-simulator-abs-commissioned-at-iowa-state-universitys-cares-lab/.

Course Instructor Biography

Dave Ritzel holds a BSc in Mechanical Engineering and MSc in Aerospace Science. He has over 45 years of experience in blast research studies covering the theoretical, experimental, and computational modeling aspects of blast physics, damage, and injury.  His research positions have included Head of Explosives Effects Group at Defence R&D Canada, and Head of Weapons Terminal Effects Group with the Defence Science and Technology Group, Australia.  In 2000, he formed his own research company Dyn-FX Consulting supporting studies of blast effects and protection technologies for Defence departments, federal security agencies, university researchers, and private industries in Canada, the US, and Australia.  For the last 20 years, his research activity has been concentrated on blast-injury biomechanics, including the special challenge of blast-induced traumatic brain injury, as well as the development of experiments and instrumentation.  He patented the “Advanced Blast Simulator” design currently used by leading research agencies in Canada, the US, and Australia.
