The <strong>Strain</strong> Ellipse<br />

• the strain ellipse allows us to<br />

describe the amount of<br />

deform<strong>at</strong>ion th<strong>at</strong> has occurred in<br />

an originally circular body<br />

•S 1 = the direction <strong>and</strong><br />

magnitude of maximum finite<br />

stretch (long axis, e 1 )<br />

•S 3 = the direction <strong>and</strong><br />

magnitude of minimum finite<br />

stretch (short axis, e 3 )
