Research Abstract

The main objective of this research is to development of new wave analysis methods for elastic wave scattering in anisotropic solids. In general, ultrasonic wave scattering in anisotropic solids are different from that in isotropic ones. Therefore, anisotropic properties may cause decrease of inspection accuracy of ultrasonic nondestructive evaluation which is one of the NDE for detecting a defect in materials. The boundary element method (BEM) is known as an effective numerical approach for transient wave analysis. However, the conventional time-domain BEM has not been applied to the simulation of ultrasonic wave scattering in anisotropic solids because the fundamental solutions for anisotropic elastodynamics are very complex and classical time marching scheme sometimes causes numerical instability for small time step size. Therefore, in this research, a new time-domain boundary element method was developed for anisotropic elastodynamics.
