Lamb wave propagation in a single lap adhesive joint
The aim of the paper is the analysis of Lamb wave propagation in adhesive joints. The research was performed on a single lap adhesive joint of two steel plates. Two types of joints, namely an intact and with defect were considered. In experimental investigations the condition assessment of the joint was performed with the use of antisymmetric Lamb waves excited by a plate piezo actuators and measured by a laser vibrometer. Numeri-cal analysis was carried out using the finite element method in Abaqus/Explicit environment. The results of experimental and numerical investigations indicated the changes in signals collected after passing through the joints with different areas of bonding.
