Microstructural Reconstruction and Three-Dimensional Mesh Generation for Polycrystalline Materials

The Department of Defense's (DoD) Materials by Design program cannot achieve its ultimate goal of discovery, design, and optimization of materials with the novel properties needed to meet current and future needs of the DoD. Government researchers do not have the tools necessary to construct realistic material models capable of making a quantitative connection with real-world materials. High Performance Technologies, Inc. (HPTi) proposes to develop a method for constructing realistic three-dimensional (3D) material models that make a quantitative connection with real-world materials and contain all of the parameters necessary to characterize the initial state of the material. The method uses a combination of experimental and computational techniques to capture the relevant features of the microstructure. It then uses this information to guide the construction of the 3D digital model. This method provides an automated microstructure and grid-generation process that produces accurate 3D digital microstructure models validated by direct comparison to experimental data. HPTi has assembled a team of researchers with expertise in computational science, material science, and grid generation and optimization. We support this technical expertise with the necessary program management, computer science, and software design expertise.
