Damage detection in plate-like structures based on polarization of Lamb waves


Simulated in-plane (H) and out-of-plane (V) signals
of Lamb wave propagating in an isotropic plate

Interpretation of Lamb waves signals can rise serious difficulties due to their multi-modal nature. Different modes
propagating with different velocities can be mislead with damage reflected components. As a solution to this
problem a technique capable of modes separation based on a polarization filter can be used.
