An Experimental Technique for Monitoring Dynamic Cracks

Abstract

A technique is presented which, by means of plating and etching processes, permits the creation of a wide variety of crack propagation gages. High precision gages of arbitrary size and shape are easily prepared. Specific gage configuration are shown for center notch, edge notch and cleavage type specimens. Optimum gage design is discussed and typical readout circuits are shown. (Author)
