Advanced Materials & Impact Dynamics

Impact

Using a synergy of our expertise regarding advanced materials and of their behaviour under dynamic impact loading conditions we focus on developing resilient materials and structures for engineering applications. Using experimental investigation, we test materials over a wide spectrum of strain rates ranging from 10-3 to 107 s-1.  

Our areas of expertise cover the study of advanced composite materials across: 

  • aerospace structures
  • automotive
  • civil infrastructure 
  • defence 
  • oil and gas industries 
  • marine industries 

Our research works to: 

  • maximise survivability by developing new protective structures for Defence to improve the performance of lightweight armour systems in defending against attacks from shape charged weapon systems and improvised explosive devices (IEDs).
  • minimise the weight burden on the soldier by developing lightweight durable structures 
  • reduce injury by developing a better understanding of the behaviour of the human body to dynamic loading and ballistic impacts.

Study With Us

We offer several courses in both advanced materials and impact dynamics.  

We also sponsor several final-year undergraduate research projects in the field of composite structural engineering. These projects relate to real-world issues faced by contemporary and future Australian Defence Force (ADF) platforms. Students participating in sponsored research projects will work collaboratively with the highly recognised Defence Science and Technology Group (DSTG). Students also develop professional career networks within our team and the wider ADF structural integrity community.
