text: In this paper, we present a method to model hyperelasticity that is well suited
for representing the nonlinearity of real-world objects, as well as for estimating
it from deformation examples. Previous approaches suffer several limitations,
such as lack of integrability of elastic forces, failure to enforce energy convexity,
lack of robustness of parameter estimation, or difficulty to model cross-modal
effects. Our method avoids these problems by relying on a general energy-based
definition of elastic properties. The accuracy of the resulting elastic model
is maximized by defining an additive model of separable energy terms, which allow
progressive parameter estimation. In addition, our method supports efficient modeling
of extreme nonlinearities thanks to energy-limiting constraints. We combine our
energy-based model with an optimization method to estimate model parameters from
force-deformation examples, and we show successful modeling of diverse deformable
objects, including cloth, human finger skin, and internal human anatomy in a medical
imaging application.
