Abstract
Based on the velocities of waves near the surface in concrete, the propagation path and travel time of different waves were calculated, and the influence of crack on these waves was analyzed. Some theoretical conclusions were verified by FEM. The ultrasonic waves were received by array transducers and the velocities of different waves were calculated and distinguished according to travel time in the simulation. Simulation results show that when sound wave propagates through the crack, longitudinal waves arrive at the receiving arrays and the crack diffracts transverse wave to generate new longitudinal wave and transverse wave by mode conversion, and the Rayleigh wave propagates along the surface (including the crack side walls). Finally it is found that the receiving signal amplitude (energy) is approximately linearly monotone decreasing with crack depth.
