摘要：
This article deals with control of a thermoelastic displacement in a composite disk consisting of a transversely isotropic structural layer and multiple piezoceramic layers of crystal class 6 mm. For various thicknesses of a specified number of layers, a stepwise electric potential distribution applied to each piezoceramic layer is determined by means of a direct optimization technique so that the thermoelastic displacement of the structural layer is controlled to a desired distribution. Based on the obtained results, an approximate optimum design problem of a composite disk is solved in order to minimize the maximum applied electric potential subject to stress constraints.
