Abstract: A Fortran program based on finite elements (FE) has been developed for
buckling analysis of thin rectangular laminated plates using classical laminated plate theory
(CLPT). The problem of buckling loads of generally layered composite plates has been
studied. The problem is analyzed and solved using the energy approach, which is formulated
by a finite element model. In this method, quadrilateral elements are applied utilizing a four
noded model. Each element has three degrees of freedom at each node. The degrees of
freedom are: lateral displacement ( ), and rotation ( ) and ( ) about the and axes
respectively. To verify the accuracy of the present technique, buckling loads are evaluated
and validated with other works available in the literature. Further comparisons were carried
out and compared with the results obtained by the ANSYS package and experimental results.
The good agreement with available data demonstrates the reliability of finite element method used.

CONCLUSIONS
The finite element model has been formulated to compute the buckling loads of
laminated plates with rectangular cross – section. To verify the accuracy of the present
technique, buckling loads are evaluated and validated with other works available in the
literature. Further comparisons were carried out and compared with the results obtained by
the ANSYS package and experimental results. The good agreement with available data
demonstrates the reliability of finite element method used.
