Summary

The differential interferometry using a Wollaston prism is now applied for experimental stress analysis. A “Differential Optical Stress Law” is derived for isotropic material which can be taken to determine the local gradient of the sum of principal stresses. After the successful application with static stress fields, the differential interferometry is now applied for studying impact problems on Plexiglass rings.
