Description

Lamb wave ultrasonic testing has been employed as a practical nondestructive method to detect defects in a thin plate. The quantitative evaluation of the ultrasonic testing has not, however, been established since the scattering process of elastic waves in a plate depends on various testing conditions such as frequencies, wave modes, a plate thickness, defect’s properties and so on. Therefore, numerical simulations for the wave scattering in a plate are necessary to make the ultrasonic method more quantitative.
