Digital Image Correlation (DIC):<br />
ARAMIS System<br />
<br />
<br />
<br />
<br />
Spray paint test sample to get<br />
random speckle pattern and<br />
using a CCD camera to take<br />
snapshots during testing.<br />
ARAMIS calculates<br />
displacement between each<br />
snapshot and a reference<br />
picture to get strain<br />
able to calculate strain within<br />
the shear zone and also<br />
localized strain during tensile<br />
test (i.e. strain in weld; HAZ<br />
and BM regions)<br />
Relate stress to strain by time.<br />
Facets in the undeformed and deformed state<br />
