WebMar 5, 2024 · e. A neo-Hookean solid [1] [2] 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. In contrast to linear elastic materials, the stress-strain curve of a neo-Hookean material is ... WebOct 12, 2024 · In the literature the Neo-Hookean material is often described as a special case of the Mooney-Rivlin material, which is an incompressible solid. In FEBio, the "neo-Hookean" material is a compressible solid based on the formulation of Bonet and Wood (1997). That's not the same as Mooney-Rivlin. So in FEBio you should use the Mooney …
