Abstract An experimental investigation of wave propagation coefficients determination of the granite was presented in the present study. Firstly, a series of pendulum impact tests were performed to investigate the stress wave properties of the granite. High-speed digital image correlation (HDIC) was utilized to capture the displacement and velocity at the free end of the impacted granite bar. Subsequently, the HDIC-based non-contact method was introduced for the determination of wave propagation coefficients of the granite. Finally, experimental studies based on the traditional contact method using strain gauges were performed to validate the present HDIC-based non-contact method. The results show that both the attenuation coefficient and wave number increase as frequency increases. Moreover, the propagation coefficients (attenuation coefficient and wave number) determined by the present HDIC-based non-contact method agree well with that determined by the traditional contact method using strain gauges. The present HDIC-based non-contact method can be used to predict the stress wave propagation through the granite effectively.
Highlights A non-contact method by high-speed digital image correlation (HDIC) was proposed.The HDIC-based non-contact method was validated by traditional strain gauges measurement.The propagation coefficients can be determined by the present method efficiently.The HDIC-based non-contact method can predict the stress wave propagation.
