Development of an ultrasonic testing simulator using the mass-spring lattice model

Abstract

Previous studies had shown that the mass-spring lattice model (MSLM) is capable of accurately simulating two-dimensional propagation, reflection, refraction, and scattering of ultrasonic waves. In the present work, models of ultrasonic probes were developed, and they were combined with the MSLM to develop a complete simulator of ultrasonic testing (UT). Several problems of typical ultrasonic testing were simulated using the developed UT simulator to demonstrate its capability to predict the waveform in ultrasonic tests.
