THE MECHANICAL AND OPTICAL CHARACTERIZATION OF SOLITHANE 113 AND INVESTIGATION OF OPTICAL LAG IN PHOTOVISCOELASTIC ANALYSIS.
Abstract
A complete mechanical and optical characterization is given for Solithane 113, a urethane rubber compound having high birefringent sensitivity and excellent optical transmission properties. Its viscoelastic transition region is found to span about six decades of logarithmic time, somewhat narrower than other materials of the urethane family. The time-dependent orientation of the principal mechanical axes and optical axes is investigated for a circular Solithane specimen subjected to a rapidly changing diametric load situation. The results indicate the possibility of large phase lag of the optical axes orientation compared to principal stress axes. The agreement with principal strain axes is generally much closer but even here the phase angle can be as much as 45 degrees. (Author)
