An integrated computational framework for modeling materials with complex and evolving microstructures
Abstract
An integrated computational framework is proposed for the automated simulation of Multiphysics behavior of materials with complex and/or evolving microstructures. The proposed methodology, which guarantees the elimination of the geometric discretization error, relies on three seamlessly integrated components: (i) A new virtual reconstruction algorithm for synthetizing realistic material microstructures based on morphological and statistical information extracted from imaging data; (ii) a novel non-iterative mesh generation algorithm allowing the implementation of a structured grid for discretizing the microstructural model and transforming that into a high quality conforming mesh; (iii) a new finite element (FE) formulation implementing a non-isoparametric NURBS-enhanced mapping for creating geometrically exact models (zero geometric discretization error) without introducing additional degrees of freedom (DOFs)
