Propagation of ultrasonic Lamb waves in adhesively bonded lap joints
This paper considers the bonded joint as a multilayer structure that is analysed using the Transfer Matrix method. In this particular case three layers (two adherents and the adhesive) are considered. The study of this propagation problem may be developed from matrix formulations which describe elastic waves in layered media. This technique combines the theory of the dynamics of the continuum w...
متن کاملComputational Models of Adhesively Bonded Joints
Simulations using the Finite Element Method (FEM) play an increasingly important role in the design process of joints and fasteners in the aerospace industry. In order to utilize the potential of such adhesive bonding, there is an increasing need for effective and accurate computational methods. The geometry and the nature of an adhesive joint are, however, not so simple to describe effectively...

متن کاملLamb Wave Interaction with Adhesively Bonded Stiffeners and Disbonds Using 3D Vibrometry
There are many advantages to adhesively bonding stiffeners onto aircraft structures rather than using traditional mechanical fastening methods. However there is a lack of confidence of the structural integrity of adhesively bonded joints over time. Acousto-ultrasonic Lamb waves have shown great potential in structural health monitoring applications in both metallic and composite structures. Thi...
متن کاملFailure of Adhesively Bonded Joints. Analysis of Experimental Results by Nominal and Local Approaches
The failure in structural adhesively bonded lap joints can be analyzed following different approaches: using a nominal stress state typically given by Strength of Material models, a local singular stress state induced at the mutimaterial corners of the joint, or using cohesive constitutive laws for the adhesive layer or other damage progression models. The aim of this paper is to analyze the su...
