Computational Capability for Designing Composite Energetic Materials under Shock and Non-Shock Loading
Abstract
This is a five-year (2 initial years and three optional years) basic research program to further develop, refine, and transfer technologically a novel computational platform for simulating the response of and designing polymer-bonded explosives. The primary condition of interest is dynamic loading of shock and non-shock nature and the primary issue of interest is the control of ignition behavior through microstructure engineering. The project is based on CODEX (Cohesive Dynamics for Explosives), a novel cohesive finite element software platform developed under a current DTRA project which is scheduled to end in early 2015. The objectives of the new project are to (1) extend the loading condition regime and material sets CODEX is capable of analyzing, (2) transform CODEX from a primarily research code to a production code for use by the larger technical community, and (3) collaborate with DoD/DoE labs to enhance the application of CODEX and integrate CODEX with other codes used by the technical community. This proposal is in support of the mission of the basic science program for the defeat of weapons of mass destruction of DTRA and concerns Thrust 4 of HDTRA1-09-14-FRCWMD-BAA. The title of the project is Computational Capability for Designing Composite Energetic Materials under Shock and Non-Shock Loading. This is a technology development project that builds on progresses made under grant number HDTRA1-10-1-0039 (4/2010-4/2015) at Georgia Tech. The primary objective of this project is to expand the physical conditions that can be analyzed by CODEX and transfer the novel technology to users in the broad technical community of energetic materials research, design and development. Specifically, the end goals are (1) extend the loading condition regime and material sets CODEX is capable of analyzing, (2) transform CODEX from a primarily research code to a production code for use by the larger technical community, and (3) collaborate with university and DoD/DoE labs to enhance the application of CODEX and integrate CODEX with other codes used by the technical community.
