Advanced Capability for Integrated Experiments and Computational Design of Heterogeneous Energetic Materials
Abstract
We propose to establish a system that integrates mesoscale experiments with computationaldesign of heterogeneous energetic materials (HEMs). The system will first advance thecapabilities of a novel experimental capability for simultaneous measurements of meso-scaletemperature and deformation fields in HEMs. Such a system is a ground-breaking, first-evertechnique for non-contact, non-intrusive diagnostics for materials at the microstructure levelusing fast infrared (IR) and visible light (VL) high-speed imaging. This proposal builds on anongoing effort at Georgia Tech (GT) in this regard and focuses on (1) enhancing the high-speedVL imaging part of the overall system and (2) establishing a gigabit data network for integrationof experiments, data acquisition/processing, computational simulations and computationalmaterials design. The IR part of the system is already the state-of-the art and based on the bestavailable technology. The proposed development will allow the VL capability to best match andaccommodate the IR capability, at spatial resolutions of up to 2.4 ?m (the IR resolution is 12 ?m)and temporal imaging rates of up to 20,000 fps (5 ?s per frame) for both and for time durationsup to 500 ?s. The primary technical factor behind this new development is the discovery thatallowing the VL side of the system to have spatial and temporal resolutions exceeding those ofthe IR side recording for longer durations (up to 500 ?s) significantly advances the noveltechnology and capabilities. The integration of experiments, simulations and computationalmaterials design will offer a first-ever platform for the development of advanced HEMs.
