Abstract

This paper presented an analysis of static and freevibration of laminated composite folded plate using finite element method, based on the first order shear deformation theory. In this analysis, a sixth drilling degree of freedom (DOF) (zθ) orresponding to the rotation about the z axis is added to the existing 5 DOF system ( u , v , w ,xθ

yθ ). The effects of fibbers orientation, crank angles (folding angle) on the deflections, onnatural frequencies of folded plate structures were determined. The present results have been compared with published one (where available). It is shown that concordance between the two sets of results.
