The nondestructive determination of the compressive component of stress in various kinds of interference fasteners is a problem of considerable interest. As noted in the previous paper,1 none of the usual techniques employed for stress measurement is appropriate for this case. This paper reports results obtained upon Nitinol couplers utilizing ultrasonic reflectivity and interpretive concepts described in that paper as advanced by Haines.2 The reader is referred to a paper in the Proceedings of the 14th Symposium, Southwest Research Institute, for full details of the present work.3
