This 5-day course is aimed at those individuals who wish to gain an advanced understanding of impact properties of materials and structures. In particular the first two days will examine the structure of materials and how the microstructure plays a role in enhancing its impact properties. Further, this course will detail the experimental and numerical techniques available to probe the dynamic behaviour of materials including the theory behind Split Hopkinson Pressure Bar operation and plate-impact experiments. When the course is held at the Australian Defence Force Academy, a demonstration using an instrumented drop tower and compression Split Hopkinson Pressure Bar will also be provided.

Professor Paul Hazell has has over 20 years of experience studying the impact behaviour of materials. He has recently moved to Canberra, Australia from the UK to take up the post of Professor of Impact Dynamics at UNSW Canberra. Before taking this position he was Head of the Centre for Ordnance Science and Technology at Cranfield University’s Shrivenham campus (at the UK Defence Academy). He has published extensively, appeared in several documentaries and presented his research work at numerous symposia. He has published two books on protection technologies with the most recent called ‘ARMOUR: Materials, Theory, and Design’ (CRC Press).
Dr J. Pablo Escobedo has over 7 years of experience in the area of dynamic behaviour of materials with emphasis on microstructural evolution and its effects on mechanical response. After obtaining his PhD he worked in premier institutions in the USA focused on the impact behaviour of materials (Institute for Shock Physics and Los Alamos National Laboratory) before joining UNSW in August 2013. He has published extensively in the area and received a TMS-Young Leader award in 2014.
