Influence Of Array Parameters On Defect Imaging In Plate By Modified RTM Method

A defect in plate is imaged and located using modified RTM method with dispersive flexural wave, and the influences of the array parameters, such as the elements spacing and the array length or aperture, on defect imaging quality are investigated. The results show that the defect position acquired in simulation is consistent with its actual position, and the imaging quality is more sensitive to th...
