What is the difference between a hyperelastic material and an elastic

WebOne of the most general hyperelastic models is the Ogden model, which is expressed in terms of the principal stretches [12]. The general form of the Helmholtz free energy per unit reference volume for the Ogden model is. (5.57) where, , and μi, αi, and κ are material parameters. The number of terms in the summation determines the order of ... WebA hypoelastic material can be rigorously defined as one that is modeled using a constitutive equation satisfying the following two criteria: [2] The Cauchy stress at time depends only on the order in which the body has occupied its past configurations, but not on the time rate at which these past configurations were traversed.
