EXACT SOLUTION FOR STATIC ANALYSIS OF AN INTELLIGENT STRUCTURE UNDER CYLINDRICAL BENDING

An exact static analysis of a simply supported intelligent structure under cylindrical bending is presented. The performance of the actuator layer of the intelligent structure to cause induced axial and transverse stresses in the substrate layer is investigated. The capability of the sensor layer to sense the deformations of the structure is shown in terms of induced electric potential on its surface. The distribution of electric potential across the thickness of the piezoelectric sensor and actuator implies that the linear variation can be adopted for choosing the electric potential function to model the laminated intelligent structure of complicated geometry and boundary conditions with refined approximate technique. The results presented here will be helpful to obtain correlation between theoretical and experimental results and to numerical analysts to verify their results.
