摘要：

Ultrasonic transducer, as a measurement technique, gains more and more attention in Non-Destructive Testing and Evaluation (NDT&E) and imaging applications. It is important to know the propagation behaviors of ultrasonic waves in both of fluids and solids. Finite element method (FEM) has been widely used to solve partial differential equations (PDE) in wave propagation. In this paper, COMSOL is adopted due to its benefits in coupling of multiphysics modules and the simplicity in postprocessing. The properties of transient wave propagation in different kinds of media, such as piezoelectric solids, nonpiezoelectric solids and fluids, are modeled and simulated. The visualized wave modes confirmed the efficiency and simplicity of this approach.
