Abstract: In this paper,the demo of ultrasonic pulse wave propagation in solid media using finite difference simulation based on Matlab soft package is presented.The rule using staggered grid with uniform spacing for acoustical wave equation of elastic wave in solid media is discussed,and absorbing boundary conditions and free boundary conditions are introduced to satisfy the assumption of a propagation in model space medium.The stability of the used schemes is controlled by a proper choice of space and time steps and the incompetent processing of animation is presented.The effects of animation are showed in the example of creeping wave propagation excited by an angle beam probe,and dynamic sound field of the numerical results are also agreed with the theoretical analysis.
