STUDY OF ULTRASONIC TECHNIQUES FOR THE NONDESTRUCTIVE MEASUREMENT OF RESIDUAL STRESS

Abstract

The theoretical and experimental investigation of ultrasonic beam interaction in solid materials was continued. Intersection of pulsed beams (3 - 15 mc) under resonant conditions r that inter action does occur in many materials. A theoretically predicted third beam is generated at the point of intersection and was experimentally observed in samples of fused silica, polycrystal line aluminum, and polycrystalline magnesium. A potential method of three-dimensional stress analysis is discussed. An optical system for studying beam interaction in transparent solids is also described.
