摘要:
Analysis of an echo from a solid elastic cylinder had been limited to the case of a plane incident wave so far. Recently, plane wave theory was modified to the case of a spherically incident wave. In this paper an arbitrary ultrasonic transmitter and receiver are considered as a set of point sources and point receivers, respectively. The analysis is modified to the practical case, that is, the cylinder is placed so that its axis coincides with the central line of curvature of a cylindrical shell transducer. The dependence of the echo from the cylinder on the cylinder material is examined. These results are compared with those experimentally obtained using metal and plastic cylinders and they show very good agreement.
