Abstract

An experimental method based on the nonlinear ultrasonic technique is presented to evaluate fatigue damage of an adhesive joint. In this paper, specimens made from AZ31 magnesium-aluminum alloy bonded through an epoxy layer are subjected to a fatigue load. The ultrasonic harmonics generated due to damage within the adhesive layer are measured; and the acoustic nonlinearity parameter (ANP) based on the fundamental and second harmonics is determined. The results show that the normalized ANP increases with the fatigue cycles. Furthermore, a theoretical model with different interfacial compression and tension stiffness is proposed to interpret the generation of second harmonics.
