| Research Abstract |
We developed a numerical procedure in three dimensions to predict electro-mechanical behavior of smart materials such as ferroelectrics and ferroelastics. Proposed procedure has ability to simulate their nonlinear electro-mechanical behavior without numerical instability, which was quite hard for conventional procedures. Promising applications of the present procedure are more accurate simulation for acceleration sensor, injector of ink-jet printer, and so on.
