摘要: Abstract We present the pre and post buckling analysis of stiffened composite panels based on finite element models. Individual studies are conducted panel madeup woven fabric CFC/epoxy, E-glass/epoxy Kevlar/epoxy composites. Straight, T shaped I stiffeners considered to stiffen panel. The is fabricated with 8 layers 16 layers, equal thickness arranged in different orientations. subjected a uniform axial compression load 10 kN. distribution stresses loads stiffener combinations estimated for three layup sequences. variation from numerical model compared experiment. results excellent agreement.
