In this research, inspection of bonding between aluminum and composite layer is simulated. To this aim, propagation of vertical wave in layers and their connection, which is created by vertical wave probe, was modelled. This simulation is performed by ABAQUS finite element software. There are three layers in finite element model, which the middle one is cohesive. To show the effect of disbond on the output signals, cohesive layer is modeled with and without hole. The results of simulated output signals were compared to test results, which was performed with nondestructive vertical wave probe, to verify the simulations. The test specimen was made of aluminum bonded to composite. In a special zone in the test specimen, dispond test was performed to compare the signals from complete bonding and nonbonding. There was good agreement between simulation and test results.
