Armour: Materials, Theory, and Design | Advanced

Course Group: 
Firepower and Protection Technologies

Building off the thee-day course of the same name, this five-day course provides participants with an analysis of the science behind the materials, systems and strategies that are used to provide protection against military and terrorist threats. Additional to the three-day course where armour materials and testing techniques have been analysed, this course will focus on the stress wave and shock propagation as well as examining active and reactive armour systems that are commonly deployed on vehicles. Wounding mechanisms and computational modelling approaches (to aid in armour design) will also be discussed.

Attendees will receive a comprehensive set of notes covering the lecture content. In addition, each attendee of this 5-day course will receive a copy of the 395-page reference book ‘ARMOUR: Materials, Theory, and Design’ (CRC Press, 2015)’. The link for the book is provided here: https://www.crcpress.com/product/isbn/9781482238297

Who Should Attend?: 

Anyone requiring an introduction to protection technologies including (and not limited to): managers; police; design engineers; civil engineers; city planners; material scientists; systems engineers; project managers (including those writing requirement specifications); serving military personnel; business managers and those working to combat terrorism.

Paul has over 20 years of experience studying the impact behaviour of materials. In 2012 he 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, 2015).
