Even though Ogden model is a hyperelastic material model, its strain energy density function is expressed by principal stretch ratio. These three models … A neo-Hookean solid is a hyperelastic material model, similar to Hooke's law, that can be used for predicting the nonlinear stress-strain behavior of materials undergoing large deformations. The model was proposed by Ronald Rivlin in 1948.
