Brief description Active shape control of large thin-walled structures using ferroelectric single crystals. Ferroelectric single crystals were invented 5 years ago, and they possess many superior properties compared to conventional piezoelectric materials, particularly the induced strain up to 1.5%, an order higher than conventional materials. This project aims to poineer the application of these new and powerful smart materials as actuators and sensors to shape control of smart structures. The expected outcomes are (a) a new constitutive theory for the non-linear behaviour of ferroelectric single crystals; (b) a novel definition and formulation for the shape control problem; and (c) an innovative theoretical framework for design optimization of shape control of smart structures using ferroelectric single crystals.
