1. Método de otimização topológica aplicado ao projeto de sonotrodos para transdutores piezelétricos. / Topology optimization method applied to the design of transducers sonotrodos piezoelectric.
This work aims at the development of a method based on Topology Optimization to design a mechanical structure, called sonotrode, which is a device usually connected to a high power piezoelectric transducer (mechanical device capable of converting electric energy into mechanical displacement or vice-versa). A sonotrode transmits mechanical vibrations of a pie

2. Study of apodization of piezoeletric ceramics / Estudo da apodização de ceramicas piezoeletricas
The objective of this work was to optimize the process of apodization of piezoelectric ceramics disks, looking for the better relation between the insulating oil bath temperature and the smaIlest period of time through which the poling field must be applied. The apodization of the piezoelectric ceramic is performed to reduce the diffraction in the acoustic f
