ACTIVE THERMAL BUCKLING CONTROL OF PIEZOLAMINATED PLATES UNDER DIFFERENT TEMPERATURE DISTRIBUTION

This paper addresses active thermal buckling control of angle-ply piezolaminated plates under uniform, linear and non-linear temperature rises. The four-variable trigonometric shear deformation theory is applied in the structural modeling. The temperature difference of upper and lower faces of plate is fed back to actuator as control voltage to control the thermal buckling. The correctness of present method is verified by comparing the frequency and critical buckling temperature with published results. The effects of geometric parameters, boundary condition, and fiber angle on the active thermal buckling control are studied. The results show that the temperature distribution strongly influences the critical buckling temperature and the active thermal buckling control method can extremely increase the critical buckling temperature of piezolaminated plates.
