Experimental Method for Simultaneous Determination of the Lamb Wave A<sub>0</sub> Modes Group and Phase Velocities

Experimental Method for Simultaneous Determination of the Lamb Wave A<sub>0</sub> Modes Group and Phase Velocities

Determining Lamb wave dispersion curves when measuring phase and group velocity values at a fixed frequency is now a common and relevant task. In most cases, in order to solve such a problem, it is necessary to know the exact properties of the material, particularly its thickness. In experimental me...
