There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Proposal Title: Fragmentation and Reaction of Structural Energetic Materials
Abstract: It is proposed to study the fragmentation and behavior of certain structural energetic materials and how these processes contribute to their reactivity. The constitutive properties of aluminum based intermetallic forming systems will be studied to quantify the physics of the deformation and fragmentation processes and the subsequent effect on reaction initiation.
Particular emphasis will be placed on the influence of microstructure morphology and composition.
The proposed research will utilize a variety of experiments including Hopkinson Bar impact and explosive fragmentation to understand the constitutive and fragmentation behavior of various material systems. These experiments will be utilized to inform and confirm a series of mesoscale simulations that will directly investigate the impact of microstructure morphology and composition on the formation of fragments and the reactivity of these systems.
The constitutive and fragmentation behavior is the key to the application of structural energetic materials to safer and more effective munitions.
Using structural energetic materials will permit the creation of more efficient and safer munitions.
