Abstract
This paper presents the numerical and experimental analyses of elastic wave propagation in a steel rod embedded in a composite material. The experiment involved the phenomenon of wave propagation generated by a piezoactuator and non-contact measurements by means of a laser vibrometer. In numerical simulations, the effect of values of elastic modulus of the material on characteristics of waves propagating in a steel rod was analysed. Conducted research presents the first stage of work focused on ultrasonic diagnostics of rock bolts.
