Control of transient thermoelastic displacement of an angle-ply laminated cylindrical panel bonded to a piezoelectric layer

摘要

In this study, the theoretical analysis of a control of transient thermoelastic displacement is developed for an angle-ply laminated cylindrical panel bonded to a piezoelectric layer due to nonuniform heat supply. By using the exact solutions for angle-ply laminate and piezoelectric layer of crystal class mm2, the theoretical analysis of a transient piezothermoelasticity is developed for a simply supported cylindrical composite panel under the state of generalized plane deformation. Analysis of a piezothermoelastic problem leads to an appropriate electric potential applied to the piezoelectric layer which suppresses the induced thermoelastic displacement in the radial direction at the midpoint on the free surface of the angle-ply laminate. Some numerical results for the temperature change, the displacement, the stress in a transient state when the transient thermoelastic displacement is controlled are shown in figures.
