ABSTRACT: Our objective is to establish a non-destructive, three-dimensional, image-based analysis protocol for inhomogeneous materials that inherently considers the heterogeneous nature of condensed matter. The process begins with a 3-D assessment of the internal material structure performed using a high-resolution micro-CT scanner. Next, reconstruction of a statistically optimal RUC will be performed such that the statistics of the cell are essentially identical to that of the micro-CT data. Finally, a validation program utilizing micro-CT mechanical and thermal testing capabilities together with statistical validation techniques and the DVC method will be conducted. Specific tasks in Phase I include: 1. Design and evaluation of appropriate experimental and diagnostic techniques for detecting the evolution of damage in representative volumes of composite materials with focus on plastic bonded explosives; 2. Identification of shortcoming of existing 3-D imaging and multiscale modeling techniques and formulate a predictive multiscale strategy for future development including assessment of potential likelihood of success; 3. Development of a general framework for predictive multiscale technology focusing on plastic bonded explosives and fiber-reinforced concrete microstructures; and 4. Performance of preliminary verification and validation studies for reinforced elastomers that mimic plastic bonded explosive. BENEFIT: The primary objective of the proposed work is to develop a truly predictive detection and simulation strategy and software toolkit capable of analyzing and designing composite materials such as plastic bonded explosives and fiber reinforced concrete using non-destructive, image-based analysis protocol. Through the complimentary expertise and software tools developed by MDS, LLC (MDS-C) and Prof. Matous (Stat3D and Recon3D) we will deliver an integrated non-destructive design system that would benefit not only typical military applications, such variety of composite materials, energetic materials and propellants, but also variety of commercial applications such as non-invasive medical diagnosis, intelligent robotics, security screening, and on-line manufacturing process control.
