WebThe primary hyperelastic behavior is defined by using a hyperelastic material model. Stress softening is interpreted as being due to damage at the microscopic level. As the material is loaded, the damage occurs by the severing of bonds between filler particles and the rubber molecular chains. Webquasi-static and an upper limiting curve. In the literature, these two curves are referred to as the equilibrium and instantaneous response curves, respectively. Assume that the material can be described by an elastic spring A in parallel with a Maxwell element B, as shown in Figure 4. Both springs in A and B are hyperelastic.
