Analysis of flexural waves excited by rectangular contact type transducers

In this paper, an attempt was made to investigate a fundamental problem rel ated to the flexural waves excited by rectangular transducers. Due to the d isadvantages of the Green's function approach for solving this problem, a d irect and effective method is proposed using a multiple integral transform method and contour integration technique. The explicit frequency domain sol utions obtained from this newly developed method are convenient for underst anding transducer behavior and theoretical optimization and experimental ca libration of rectangular transducers. The time domain solutions can then be easily obtained by using the fast Fourier transform technique. (C) 2001 El sevier Science B.V. All rights reserved.
