Static and dynamic analyses of stiffened folded laminate composite plate

Abstract

This  paper presents some numerical results of bending and vibration analyses of an unstiffened and stiffened folded laminate composite plate using finite eleraent method. Tee eeffects of fìber orientations, boundary conditions, suffener conditions of the plates for deflections, natural frequencies, and the corresponding mode shapes, transient displacement vesponses were considered The Matlab programming using lectangular isoparatnetrc plate element with five degree of freedom per node based on Mindlm plate theory were built to solve thr problems. A good agreement is found between the results of this technique and other published results available in the literature.
