Must Elastic Materials be Hyperelastic?Department of Mechanical Engineering and Materials Science, Rice University, Houston, TX 77251-1892, USA Rivlin's observation that elastic stress response that does not derive from a strain energy (Cauchy elasticity) admits negative work in closed cycles of deformations is demonstrated for specific isotropic stress responses and for a simple closed cycle of deformation. It is concluded that elastic materials must be hyperelastic.
Key Words: finite elasticity Cauchy elasticity hyperelasticity strain energy
