ANALYSIS OF ADAPTIVE LAMINATE WITH PIEZOELECTRICAL MATERIAL LAYERS

If piezoelectrical material has been used as one of the layers of composite material laminate, the laminate becomes so called piezoelectrical adaptive one, which has not only the load bearing capacity, but also the measuring and actuating capacity. In this paper, the actuating effect of piezoelectrical element is changed for an equivalent mechanical load, and the piezoelectrical adaptive laminate is analyzed with the classical laminate theory. The theoretical results satisfy the experimental ones very much.
