Abstract:

The proposed research aims to generate the fundamental knowledge base that specifically focuses on the effect of the variability of the material properties especially interface properties and mesoscale morphology on the dynamic response and hot spot formation in heterogeneous energetic materials. To achieve this aim, this research 1 experimentally characterized and quantified the interfacial dynamic properties and their variability at the length scale of the meso- and microstructure 2 establish the mesoscale structure property relationships and sensitivities that characterize the dynamic behavior in the presence of uncertainties. The research focused on the HMX-HTPB and AP-HTPB material systems.
