Research Abstract

In order to develop design criteria to ensure the reliability and long-life capability of eco-friendly hydrogen fuel injectors for clean energy cars and rocket engines, we investigated the effects of microstructures, localized domain switching, domain wall motion etc. on the electromechanical properties and mesoscopic fracture/fatigue properties of piezoelectric material systems (e. g. multilayer piezoelectric actuators)under severe environments theoretically and experimentally.
