An Integrated Computational Framework for Modeling Materials with Complex and Evolving Microstructures

Abstract

The project focused on developing an automated computational framework for modeling materials with complex microstructures. Main achievements include: (i) Establishing a parallel, noon-iterative mesh generation algorithm named CISAMR for meshing high complex domain geometries with super-linearspeed-up in parallel enabling the construction of massive meshes with tens of millions of degrees of freedom; (ii) Developing a microstructure reconstruction algorithm consisting of virtual packing and optimization phases, for synthesizing realistic micro-structural models of various materials including fibrous composites, particulate composite, and entangled non-woven fibrous materials; (iii) Implementing the meshing and virtual reconstruction algorithms for modeling several real-world problems, including asteroidal rocks, fiber reinforced composites, and structural adhesives.
