As a result, … Web252 Constitutive Modelling of Solids and Fluids 12.4.3 The Incompressible Neo-Hookean Model The Neo-Hookean model provides a reasonable description of the behaviour of rubber-like materials at finite strains and is also quite often used for biological materials. Rubbers behave nearly incompressibly, which is also valid for many biological materials … WebApr 7, 2015 · In the section after, we are left with the Simo and Pister model and the Compressible neo-Hookean model, and decide on Simo and Pister's model [1] for further study. Presented is a general form of invariant-free hyperelasticity (the so-called generalized strain energy function), and the fitting of the Simo and Pister model into that framework. breaking knee adhesions
