Abstract
Thermal buckling analysis of a laminated hybrid beam with surface mounted piezoelectric layers is presented in this work. A one dimensional finite element (1D-FE) model based on efficient layerwise (zigzag) theory is used for the analysis. Two noded and three noded 1D elements are utilized for interpolating electromechanical and thermal variables respectively. Piezoelectric layers are bonded to top and bottom surfaces of the elastic substrate of hybrid beam.The beams are subjected to uniform temperature with closed circuit condition at top and bottom surfaces. The thicknesses of piezoelectric layers are varied and its effect on critical buckling temperatures is studied. Results are presented for composite and sandwich beam configurations under simply supported boundary conditions. The 1D-FE results are compared with the 2D-FE results obtained using commercial FE package ABAQUS.
