| Research Abstract |
For sensor or actuator devices using functional materials, which exhibit elect-mechanical or magneto-mechanical coupling, we have developed a numerical simulation procedure not only to predict their physical behaviors but also to utilize the present numerical procedure for their designs in industry. In the development we haveunified electromagnetics within the framework of conventional elasticity in terms of thermo mechanics, and have also made it mathematically consistent and rational. Our main topics are
(1) numerical study on elasto-plastic-type constitutive laws for nonlinear piezoelectricity and
(2) development of a structural optimization procedure for magneto-strictive actuators.
