Abstract
Multilayered metallic structures, such as adhesively bonded aluminum plates, are increasingly used as construction elements for their reduced weight and strong mechanical properties. However, non-destructive inspection of these components is challenging due to multiple reflections and mode conversions in traditional ultrasonic scans. Laser ultrasound (LU), a fully optical, non-contact technique, offers fast and efficient inspection with high-resolution performance. LU generates a broad range of frequencies, and shear modes can be efficiently produced in the thermoelastic regime using low laser energies. This paper analyses the resolution of a laser-generated shear wave technique for inspecting adhesively bonded aluminum plates. Multiphysics finite-difference simulations are performed on a two-layer aluminum plate model bonded with an epoxy film, incorporating a defect simulating delamination. Various defect depths are examined to evaluate the technique’s resolution, and the simulation results are validated through experiments on a structure composed of three aluminum plates bonded with an epoxy film.
