Abstract :
This paper concerns a multiobjective optimization problem for an underwater ultrasonic transducer based on the porous piezoelectric ceramics. The number of the design variables was decreased using the obtained dependences for the effective characteristics of PZT material on porosity. The optimization problem based on the Pareto-frontier calculation has been solved using the live-link of finite-element (FE) package Comsol Multiphysics with MATLAB.
