Abstract
Dynamic photoelasticity is a full field technique which has been used by various researchers as an aid to improve understanding of problems that involve stress wave propagation. Birefringent materials that exhibit sufficient sensitivity to loading for stress wave propagation studies are typically polymers. Glass, which is not nearly as viscoelastic as polymers does not exhibit enough sensitivity for easy measurements, thus it is unsuitable for most dynamic studies. The effect of loading rate on material properties is more pronounced in polymers, hence accurate measurement of these properties is essential in a dynamic photoelastic study. The problem associated with the determination of the dynamic material properties of a polymer is the determination of the exact location of the wavefront. Digital image analysis can be used to locate the wavefront with a great deal of accuracy. The results from the digital image analysis can then be used to determine dynamic material properties for the polymer. Copyright © 1994, Wiley Blackwell. All rights reserved
