| Research Abstract |
A multilayer composite circular plate consisting of a structural layer with heat resistance, a piezoelectric sensor layer, and some piezoelectric actuator layers is taken as an analytical model in this study. We have developed a method which provides an intelligent function for autonomously controlling the transient maximum thermal stress in the structural layer so as not to exceed its allowable stress, adapting to an unknown thermal loading acting on the structural layer. Furthermore, we have developed a method for optimally designing the multilayer composite circular plate so that the performance of the intelligent function is at its maximum. Then, the optimally designed model is presented and the highest suppression ratio of the maximum thermal stress is revealed.
