Hyperelastic Material<br />
Hyperelastic (rubberlike) materials<br />
exhibit an incompressible response,<br />
path independence <strong>and</strong> no energy<br />
dissipation.<br />
<strong>The</strong> stress is now calculated through<br />
<strong>the</strong> strain energy functional W<br />
t<br />
0S ij = ∂W<br />
∂ t 0ɛ ij<br />
