And that's where the trouble begins, as Professor Rosakis learned from his experiments with 5mm thick transparent blocks of photoelastic polymer with a hairline fracture in each of them (pictured below right) containing a thin exploding wire that is transformed into plasma once triggered, thus simulating the San Andreas fault, i.e., a strike-slip (right-lateral) fault, during an Earthquake.

Gerber, a junior in mechanical engineering, works as an undergraduate research assistant to Dr. Paul Hubner, assistant professor of aerospace engineering and mechanics, and focuses his research on using luminescent photoelastic coatings, a new experimental method for stress analysis, to advance coating calibration and performance.

The argument, essentially, is this: Birefringence arises because the molecular chains in the photoelastic polymer get stretched.
