Synopsis

Terrorist bomb attacks and threats are on the rise all over the world. It is estimated that most injuries from bomb blasts can be attributed to airborne sharp glass fragments. Therefore, it is essential for us to thoroughly understand the failure mechanism of glass under blast loading in order to develop better blast-resistant transparency and to mitigate the injury due to flying glass fragments. This is an international joint project between the University of Sydney (Usyd) in Australia and the University of Missouri-Columbia (UMC) in USA. The potential PhD student at Usyd will be mainly working on the numerical modelling part of the project with the corresponding experiments being performed at the UMC.
The objective of the numerical and modelling part is to develop a multi-scale bifurcation-based decohesion model within the framework of the Material Point Method (MPM), one of the meshfree methods, for simulating glass fragmentation under blast loading. The proposed multi-scale decohesion model will be calibrated by combining molecular dynamics and continuum mechanics approaches, and the simulation results will be verified by available experimental data.
