Energetically Consistent Invertible Elasticity.
Eurographics Symposium on Computer
Animation (SCA) 2012.
We devise an energy-based approach for extending isotropic hyperelastic
constitutive models to handle inverted configurations.
We also develop a new tool for analyzing and improving
the behavior of constitutive models. We demonstrate
improvements on the inverting finite element method
and the popular corotational model.
