Characterization of Adhesively Bonded Joints Using Acousto-Ultrasonics

摘要

The mechanical performance of adhesively bonded joints is characterized using nondestructive acousto-ultrasonic and destructive shear testing techniques. The research program is intended to assess the feasibility of utilizing acousto-ultrasonics in characterization and strength prediction of adhesively bonded joints. The basic principles of the acousto-ultrasonic technique are described. The instruments, operating procedures and factors affecting acousto-ultrasonic measurements are explained. Factors affecting the joint strength such as the material and geometry of the joint are also discussed. Experimental results obtained in a series of characterization tests on adhesively bonded specimens are presented.
