概要
Abstract Ultrasonic guided waves have been widely applied to the long-range inspection of straight piping. Guided waves have many wave modes with different sound velocity. So, ultrasonic testing beyond welds and elbows is very difficult to interpret testing data. This paper reports the simulation and visualization of guided wave propagation via a large-scale 3D FEM code, which has over one billion elements and parallel computing system. The prediction of torsional guided wave propagation and reflected signals beyond two elbows is presented.
