WebJun 2, 2015 · Two basic incompressible material models are presented, incompressible Neo-Hookean and two-parameter Mooney–Rivlin ; however, presented methods may be easily extended to the higher-order material models. The incompressibility of the materials is ensured in the current study by the penalty method, which ... WebApr 17, 2024 · The Neo-Hookean model is the simplest form of all commonly used hyper-elastic models. The elastic strain energy potential energy is expressed as. Where u is the initial shear modulus. D1 is the material’s incompressible parameter. It can be found that the model is a strain energy function based on the strain tensor invariant I_1.
