Simulation of the finite element method on wave propagation in cylinders

This paper studied the application of finite element method (FEM) in analyz ing the propagation of elastic wave's in cylinders. The spatial and tempora l steps of discretization of the finite elemental computation are discussed . The displacement fields excited by a pulsed tine-source with 5 MHz center frequency in cylinders are computed and displayed by color images. The wav e forms of receiving points in the surface of the cylinders, identified as A-scan results, are also shown. The comparison between the finite elemental and experimental results show that FEM is a good way for the simulation of the wave propagation in cylinders.
