Finite element modeling of composites and sandwich laminates

a.INTRODUCTION The rapid increase in the industrial use of the advanced composite materials (Fibre Reinforced Laminated Composites) is considered as one of the important development in recent past. Better performance of these composite materials over conventional metallic materials has encouraged their use as structural materials in a wide range of engineering applications all over the world. b. ABSTRACT Laminated composites and sandwich plates have been widely used in civil, mechanical, aerospace, marine and other branches of engineering due to their high strength/stiffness to weight ratio and good tailoring capability compared to the conventional materials. However, laminated composite materials are weak in shear due to its low shear modulus compared to extensional rigidity. This phenomenon is quite significant in case of laminated sandwich plates due to wide variation of materials between the core and face sheets. . APPLICATIONS 1. Aerospace Engineering 2.
