Enhancement of the dynamic buckling load for a plate by using piezoceramic actuators

We consider geometric and material nonlinearities when studying numerically the transient three-dimensional elastic deformations of a plate with piezoceramic elements perfectly bonded to its top and bottom surfaces, and analyze the effect of the shape and the size of the piezoceramic actuators on increasing the buckling load of the plate. The applied compressive edge load is assumed to increase linearly with time and the plate is taken to have buckled when the maximum transverse deflection at a point equals three times the plate's thickness.
