Optimization of 1-3 Piezocomposite Material Structures for Underwater Acoustic Transducer

摘要

Performance of piezocomposites depends on such design variables as the properties of constituent materials and structural geometry of the composites. Values of the design variables are determined to increase a predefined figure of merit of the application envisaged. In this work, a new method to optimize the design variables of 1-3 piezocomposites has been developed to maximize the electromechanical coupling factor in a much more efficient and systematic way. The technique is so general that it can be applied to any other piezoelectric materials and connectivity as well.
