This article describes the results of experimental evaluation of capabilities of a pin-force mathematical model for guided wave generation and sensing in elastic beam-like structures using MFC piezoelectric elements. It is found that the model provides an adequate and convenient tool for fast parametric study of wave excitation and propagation at a frequency range of practical interest. The model is tested against both MFC and laser vibrometer-based signal measurements; the upper frequency limits of applicability for both sensing methods are demonstrated.
