DESCRIPTION:Impact sensitivity (literally\, how hard do you need to hit a 
 material to cause it to initiate) is a critically important safety metric 
 and performance indicator for explosives. It’s a challenging property to
  measure experimentally\, however\, which has fuelled the need for physica
 l models to understand the link between structure and material property. W
 hile predicting property from structure is valuable\, perhaps an even grea
 ter prize is having the ability to run the process in reverse\, i.e. to pr
 edict structures likely to present with a desired property. In this talk I
  will outline\, (i) how we can link impact sensitivity to structure throug
 h a first-principles physical model\, and (ii) how we can broaden out the 
 pool of structures studied through a supervised machine learning study\, u
 sing features derived from the physical model. The output from this work a
 re tools that can guide the discovery\, design and synthesis of safer expl
 osives.
