This five-day, 10-module online simulcast course will equip the students with a comprehensive view of Explosive Materials and provide participants with an introduction to chemistry and its application to detonable material systems. Mechanisms of deflagration and detonation as well as the effects of explosive blast will also be explored.
This full course comprises of 10 modules each of which correspond to approximately 3 hours of directed learning activity.
At the end of this course, the student will be able to:
LO1 Explain basic chemical principles relevant to explosives science, including stoichiometry, chemical bonding, intermolecular forces, thermochemistry and reaction kinetics (including detonation vs deflagration);
LO2 Discuss the differences between types of explosives;
LO3 Explain the application for each type of explosive and show how each type can be used in an explosive train;
LO4 Discuss IM-compliant munitions;
LO5 Explain the different types of stimuli that will lead to detonation of an explosive;
LO6 Explain the way a detonation evolves within the explosive composition and how these waves are sustained;
LO7 Describe shock-wave theory (including equations-of-state); Rankine-Hugoniot theory and C-J theory.
PROFESSOR PAUL HAZELL
Paul 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).
ADRIAN GARRIDO SANCHIS
Dr. Adrian Garrido Sanchis is a Chemical Engineer that works as an Associate Lecturer at UNSW School of Science, in Canberra, where he lectures chemical and biological weapons and explosives. He specializes on developing new technologies for explosive detection and the purification and sterilization of wastewater from bench to commercial scale applications. He has pioneered the development of a novel sterilization process, which has been adopted by Australian Pork Limited (APL), who have recently funded his research and have funded the development and construction of a small scale water treatment pilot unit which has been trialled at a piggeries water treatment plant in NSW. He submitted a provisional patent application via UNSW to seek protection for this new process.
Adrian has substantial experience in commercial R&D and a unique range of abilities and skill set in water treatment and automation/environmental monitoring through IoT devices.
