Hyperelastic warping
Web30 jan. 2013 · Hyperelastic warping is the process in which an energy functional is minimized. This energy functional consists of the total hyperelastic strain energy from the material model and the image based term ( 2 ). The total energy takes the form: where is the Jacobian and is the left Cauchy-Green deformation tensor.
