Enhancement of Buckling Load of Thin Plates Using Piezoelectric Actuators
Thin plates which are used in most aeronautical and aircraft structures are often subjected to form failures called buckling. Certain passive techniques such as adding stiffeners increase the buckling load, as well increases the weight of the system. Aesthetic considerations and limited availability of space and weight restrict the use of stiffeners. Hence it is necessary to resort to certain active control techniques such as usage of smart materials to control the deflections under operation. Several researchers have used PZT actuators for vibration control of columns.
