Investigation of Microscopic Mechanisms of Failure of Electronic Smart Materials/Systems

Abstract

The objectives of this investigation are the following: (1) Understand the microscopic mechanism of formation of microcracks in these ferroelectric ceramics; (2) Quantify the dependence of the strength of these ceramics upon their microstructural parameters, that can be controlled through the manufacturing processes; and (3) Tailor these ceramics for maximum strength by optimizing the microstructural parameters.
