Résumé

A numerical-experimentalstudy of the displacementsdistribution and the radiated field of various (directiona]and focusing)f1exura] plate transducersis presented.The numericalmethodbasicallyconsistsof calculatingthe distribution of displacementsof the transducersby the finite element method by using the code ATILAwhile the corresponding radiated field is calculated by the boundary element method by means of the code EQI. In this way the near and far field of the transducersis calculatedas well as their directivitypattern and vibrationdistribution.The obtainedresults are compared with experimentaldata. The good agreement obtained indicatesthat the numericalmethod used in this paper is a very useful too] for calculatingthe fieldof transducersand for the optimisationof their design.
