Polycrystalline Microstructure Reconstruction and Meshing

Thermo-mechanical processing of ceramics and metallic alloys, some polymers and composites comprised of a mixture of these materials exist as bulk aggregates of single crystalline lattices. Understanding the physical mechanisms responsible for the dynamic response of those materials subjected to large strain at high stress rates is very important. From experimental observations statistical data describing the newly developed materials are available. The objective of this SBIR is to define a set of interoperable software components to support the effective reconstruction and meshing of the microstructures, and tie them together through a graphical user interface. In detail, this SBIR will provide tools that (i) produce 3D microstructures for polycrystalline materials from the given statistical description of these microstructures, (ii) quantitatively gauge the accuracy of the microstructures with regards to the given statistics, (iii) create a non-manifold boundary representation appropriate for automatic mesh generation from the microstructure, (iv) mesh the non-manifold boundary models and provide adaptive control of the meshes generated, (v) allow the user to control the definition and execution of the reconstruction and meshing process through a graphical user environment.
