Witryna12 kwi 2024 · Materials exhibiting recoverable large nonlinear elastic deformations like polymers, elastomers and biological tissues can be characterized as isotropic hyperelastic materials. Hyperelastic materials are favored in applications where high flexibility and high durability are required in the presence of high loads. WitrynaHyperelastic 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.
