Development of "Smart" Piezothermoelastic Laminae: Theory and Applications.
Abstract
Active 'smart' structures with self-sensation, action and reaction capabilities can lead to a major technology breakthrough for the next-generation high-performance structures and mechanical systems. This new emerging area encompassing sensors, actuators, electromechanical systems, active materials, controls, and structural continual can be defined as the structure-electronics - StrucTronics. Among the commonly used sensor/actuator materials, piezoelectric materials possess unique electromechanical properties (the direct and converse piezoelectric effects which can be respectively applied to sensor and actuator applications. The main objective of this research is to study the multi-field piezothermoelastic phenomena of piezoelectric laminae and to investigate the thermal effects to the performance of distributed piezoelectric sensors and actuators. There are three research components: ( 1) to develop new generic piezothermoelastic shell lamination theories, (2) to formulate piezothermoelastic finite elements and associated sensing/control numerical capabilities, and (3) to validate analytical and/or finite element solutions via laboratory experiments. This report includes all three aspects of the piezothermoelastic research. As described in the standard ARO Report Instructions, this report begins with Statement of Problems Studied, and followed by Summary of Research Results. Lists of technical publications and participating personnel are also provided. (MM)
