Elastic Material<br />
For an elastic material <strong>the</strong> stress is a function <strong>of</strong> strain only <strong>The</strong><br />
stress path is <strong>the</strong> same both in loading <strong>and</strong> unloading<br />
<strong>Linear</strong> Elastic<br />
<strong>The</strong> elasticity (constitutive)<br />
tensor components, C ijrs are<br />
constant<br />
<strong>Non</strong>linear Elastic<br />
<strong>The</strong> elasticity (constitutive)<br />
tensor components, C ijrs are<br />
a function <strong>of</strong> strain<br />
Example: Almost all materials under small stress<br />
