Numerical Simulation of the Ultrasonic Pulse Wave Propagation at Solid-Solid Interface

In order to visually display the propagation of ultrasonic pulse wave along the solid-solid interface, a finite element model with two kinds of glass was developed to simulate the ultrasonic propagation at solid-solid interface. The snapshots clearly display the ultrasonic propagation along the solid-solid interface with two kinds of glass. The simulation results are in agreement with the theoretical and experimental results. The simulation showed that the finite element simulation method can properly display the propagation of ultrasonic pulse wave at the solid-solid interface, and can observe clearly the complex sound field formed at the interface, so it may offer some reference for ultrasonic nondestructive testing technology in selecting the best testing parameters and defects feature extraction.
