Abstract

Abstract: This paper presents an investigation of wave propagation through granite after different high-temperature treatments by using a pendulum impact setup. Propagation coefficients (attenuation coefficient and wavenumber) were successfully introduced to describe the attenuation of longitudinal waves through granite after high-temperature treatment. The attenuation rate of the longitudinal wave through the granite after different high-temperature treatments was obtained. In addition, the effects of temperature, amplitude and wavelength of longitudinal waves on the propagation coefficient and attenuation rate were discussed. The experimental results show that the propagation coefficient and the attenuation rate increase with increasing temperature. The attenuation rate decreases with increasing wavelength, while the propagation coefficient is not influenced by the wavelength. Meanwhile, the propagation coefficient and the attenuation rate are not influenced by the amplitude of the longitudinal wave.
