Anisotropic Elasticity for Inversion-Safety and Element Rehabilitation Theodore Kim, Fernando De Goes, Hayley Iben July 2019 We present an analysis of anisotropic hyperelasticity, specifically transverse isotropy, that obtains closed-form expressions for the eigendecompositions of many common energies. We then use these to build fast and concise Newton implementations. We leverage our analysis in two separate applications. First, we show that existing anisotropic energies are not inversion-safe, ... more Paper (PDF) Video Additional materials: [Anisotropy2019_supplement.pdf], [matlab.zip] |
