Challenges in Computational Mechanics: Isogeometric Trimmed Shells, Imaging-driven Microstructure Upscaling and Variational Multiscale Modeling
Dominik Schillinger
Civil, Environmental, and Geo- Engineering, University of Minnesota
ABSTRACT: This seminar revolves around three problems from different areas of computational mechanics, illustrating the broad spectrum of research that is currently underway in Schillinger's research group. Schillinger first talks about the current disconnect between computer-aided geometric design (CAD) and finite element analysis in today’s design-through-analysis workflows. In the second part, he explains how the anisotropic and heterogeneous properties of plant materials are related to microstructure composition at different length scales. In the third part, he talks about a new interpretation of discontinuous Galerkin methods through the lens of variational multiscale analysis, arguing that the resulting coarse-scale formulation represents a general unifying framework for deriving specific variants of discontinuous Galerkin methods. Schillinger closes by outlining potential engineering applications.
