Under the condition of vertical stress and ultrasonic propagation, a practical formula for measuring the surface acoustic wave velocity of the dual-probe under uniaxial stress state is established. The surface acoustic wave transducer used for surface inspection of the transparent aeronautic material is developed. Using surface wave propagation velocity and surface Stress-dependent relationship between the center of the hole YB-3 transparent pieces of the typical pieces of the sample were stress concentration state of the acoustic bouncing test, at the same time by means of strain gauges made a comparative experiment. The experimental results show that the local stress acoustic bomb detection method is reliable and effective.
