Behaviour of FRP composite panel subjected to In-plane loading

Abstract

This paper deals review of the research on buckling behaviour of stiffened panels, which has been conducted in recent years by using finite element method (FEM) analysis, analytical method and experimental work. The review paper also deals postbuckling behaviour of fiber-reinforced polymers (FRP) stiffened panels with delamination-damage under compression and shear. Many experimental and analytical studies have been performed on the pre-buckling and post-buckling behaviour on laminated composite panels under axial compression. Most of the researchers have worked on the composite panel by using blade type, I section, T section and hat stiffeners. A very few literature are available on trapezoidal type stiffener of panels with respect to the specific depth of stiffeners but a variation of depth of stiffener has not been included in parametrical studies on buckling behaviour of composites panel by 3D-FEM. Non-linear finite element (FE) model has been used to perform parametrical studies on debonding between skin and stiffeners. © IAEME Publication
