WebHyperelastic Material Models. A hyperelastic material is defined by its elastic strain energy density Ws, which is a function of the elastic strain state. It is often referred to as the energy density. The hyperelastic formulation normally gives a nonlinear relation between stress and strain, as opposed to Hooke’s law in linear elasticity. WebThis is due the neo-Hookean, Ogden and Yeoh models [50]. to the fact that the vertical load in the bearings (which was not measured Assuming an incompressible material, the Ogden strain energy during the experiments) is expected to decrease with increasing lateral function depends on the three principal stretches λ1, λ2, λ3 and 2 N displacement.
