LRIR Proposal- An Efficient Solution Method for Large-Scale Progressive Fracture Simulations of Advanced Composite Materials
Abstract
Multiscale methods have enabled many successes in capturing the multiscale nature of composite materials. However, nearly all such approaches rely on a periodic unit-cell that can be mathematically leveraged to make the simulations tractable. This project aims to develop a novel solution method that focuses on both the multiscale nature of composites and a solver that enables the direct simulation of fracture across length scales for complex composite components. We hold that a solution method that leverages both grid coarsening and model coarsening, that is, physics models designed for different length scales, can circumvent the limitations of multigrid methods and converge faster than general-purpose solvers for large simulations. The proposed work will open a new frontier of integrated computational materials engineering (ICME) by enabling component-level performance simulations that directly consider the micro-mesoscale.
