Finite element study on random design of 2-2 composite transducer

Random 2-2 composite transducers are studied using FEM(ANSYS). Admittance curves as well as beam patterns in the near field are calculated and are used to evaluate the performance of random 2-2 composite designs. First, the pressure and the normal velocity distributions at the interface of water and transducer are calculated using ANSYS, then, these pressure and velocity are used to calculate the beam pattern using Helmholtz integral. Different random configurations are studied and the results are discussed.
