Description

Methods for nondestructive evaluation of adhesive joints have been extensively discussed in the literature because of the technological importance of the problem and the extreme difficulty of evaluation of interphasial properties [1]. Several methods have been proposed for adhesive joint interphase evaluation: ultilization of interphase [2,3] or guided [4–8] waves in the bonded plates or use of obliquely incident ultrasonic waves analyzing signals in the time or frequency domains [9–14]. Most of the above studies (except [5]) have evaluated the adhesive bond in bonded areas away from the sample edges. Even when the configuration of the experimental samples included the edges [2–7] wave scattering and transformation on the edges was neglected. The edge effect and the transformation of Lamb waves at the edges are the main topics of this work. Some preliminary results in this direction were reported in our previous work [5].

Application of Lamb Waves for Evaluation of Lap-Shear Adhesive Joints

La Jolla, CA

Methods for nondestructive evaluation of adhesive joints have been extensively discussed in the literature because of the technological importance of the problem and the extreme difficulty of evaluation of interphasial properties [1]. Several methods have been proposed for adhesive joint interphase evaluation: ultilization of interphase [2,3] or guided [4–8] waves in the bonded plates or use of obliquely incident ultrasonic waves analyzing signals in the time or frequency domains [9–14].
