Methodology to evaluate variations in piezoelectric constants after aging process

Piezoelectric ceramic properties change with time. Detected aging effects for PZT ceramics are, the difference in the value of the dielectric constants diminishes, whereas dielectric losses and elastic stiffness increases. In this work, an optimisation technique based on adjusting a finite element m...
