Experimental Verification of Various Modelling Techniques for Piezoelectric Actuated Panels

The scientific equipment being used on-board satellites sometimes requires a high degree of pointing accuracy and a minimum level of disturbances i.e. vibrations. To this end, actively controlled structures are employed and one of the best methods of achieving this degree of control with the minimum of impact on the structure itself is to employ piezoelectric patches as sensors/actuators. In th...

Free vibration Study of simply supported cylindrical laminateds panels with piezoelectric layer

In the present study, vibration of cylindrical laminates with different layers and angles were studied. In order to actuate and polarize in radial direction, a piezoelectric layer was located at outer surface of composite shell. Laminates were assumed long enough so that plane strain state analysis in 2D can be used properly. In order to satisfy the boundary conditions, variables in terms of Fo...

Buckling Analysis of Thin Functionally Graded Rectangular Plates with two Opposite Edges Simply Supported

In this article, an exact analytical solution for thermal buckling analysis of thin functionallygraded (FG) rectangular plates is presented. Based on the classical plate theory and using the principle ofminimum total potential energy, the stability equations are obtained. Since the material properties in FGmaterials are functions of the coordinates (specially the thickness), the stability equat...
