Abstract

Shear wave birefringence in metal specimens has been studied as a possible method of nondestructively measuring residual stresses. It has been established that the stress-induced birefringence in aluminum and steel varies linearly with the magnitude of an applied stress and does not change appreciably as these metals are deformed plastically. Other sources of birefringence were studied also. Preferred orientation is a major source especially in rolled metal stock. A pulse echo technique for observing shear wave birefringence is described and the current limitations are discussed.
