| Descripción: | This paper discusses a three dimensional implementation of boundary integral equation method (BIEM) for large scale time domain elastodynamic problems and its application to ultrasonic nondestructive evaluation (NDE). We improve the time integration algorithm of the BIEM in order to reduce the required computational time. We show the e±ciency of the proposed method by applying it to a simple wave scattering problem and to a more realistic crack determination problem related to ultrasonic NDE. |
