Compatible Parameterizations based Isogeometric Analysis of Fluid-Structure Interaction with Applications in Blast Mitigation

Abstract

Our first goal is to understand how compatible parameterizations (tensor-product splines and triangular splines) in structure and fluid domains enable new spatial and temporal strategies for coupling isogeometric structure solver and isogeometric fluid solver to obtain more accurate and efficient coupled multiphysics analysis. Our second goal is to further develop compatible parameterizations based analysis and optimization algorithms and apply them in optimal design of shape and material distribution in 3D deformable plate structures under blast load.
