Abstract

Abstract: The present paper deals with the prediction of thermo elastic behavior of the thin four-layered Angle- ply Hybrid Fibre Reinforced Plastic (FRP) skew laminated composite plate with circular cut out by considering two composite materials Graphite-Epoxy and Boron-Epoxy materials which are subjected to uniform pressure load and thermal loading. The problem is modeled in ANSYS software based on the Classical Lamination Theory (CLT) which is suitable for the analysis of thin laminates with circular cut-out. The effect of size of the circular cut out and skew angle on the stresses are shown for Angle-ply laminates. The principle stresses and shear stresses are evaluated for different cross sections. The present analysis is useful for the safe and effective desi gn of the skew laminates with circular cut out under uniform pressure load and thermal load conditions
