Web16 okt. 2024 · Hyperelastic models (as the name implies) deal with elastic materials - those which deform when a load is applied, and return to their original shape after the load is released. Unlike Hookean elastic models, which have a linear strain-stress relationship, hyperelastic models have a non-linear relationship:
