abstract

As new compositions of single crystal relaxor ferroelectrics are developed, the full thermo-electro-mechanical characterization of each composition and the limitations on linear behavior imposed by field driven phase transformations requires a highly specialized set of experiments. This characterization currently requires two crystal cuts which must each be subjected to five electric field-electric displacement cycles at different stress levels, five stress-strain cycles at different electric field levels, and this process must be repeated at five temperatures. In this document, a new approach to characterizing the linear behavior and phase transformation behavior is proposed based on a combination of a work-energy based model of the driving forces for the phase transformation together with data measured through electrical loading while measuring strain and electric displacement, and a measurement of mechanical compliance.
