Abstract

The ultrasonic non-destructive evaluation (NDE) has been particularly important in maintaining civil and nuclear power structures. The goal of ultrasonic NDE is to determine the shape and volume of defects. Inverse scattering analyses have been developed by researchers to reconstruct a defect in isotropic materials. However, there have not been many researches on inverse scattering method for complicated materials, such as viscoelastic and anisotropic materials. In this research, an inverse scattering method is developed for a defect in viscoelastic materials. In addition, a new time-domain BEM for visco-elastic wave propagation is utilized to numerically obtain scattering waves by a defect.
