Determination of group velocity of propagation of Lamb waves in aluminium plate using piezoelectric transducers

A prior knowledge of group velocities of Lamb wave modes is a key for analysis of time signals in guidedwave based structural health monitoring. The identification of multiple wave modes may be complicated due to dependency of group velocity on frequency (dispersion). These dependencies for infinite...
