Abstract
In recent years, usages of composite materials have progressed in automobile, aerospace industries and it is one of the alternatives for metal materials. This trend is because of their high strength to weight ratio and also it is possible to manufacture components as per required mechanical properties. Therefore the role of stresses is very important in composites. Hence an accurate understanding of their structural behavior is required, such as stresses both normal and shear stresses. Numerical analysis has been carried out for Graphite/Epoxy Composite laminate to find the stresses of a laminated composite plate subjected to axial loads along X & Y directions of the specimen. In the numerical method, the stresses are developed for plies of orientation (00/300/-450) in the laminated composite and simulate the numerical values developed using HYPERMESH 13.0 for validation. This work presents a stress analysis of Graphite/Epoxy laminated composite plate. In the present work, the stress behavior of laminated composite plates under Tensile loading using a four-node element with six degrees of freedom at each node and translations in the x and y directions is done. The static stress analysis includes the all types of stress behavior in diagrammatic form and results are plotted for investigation. In the present study, the modeling is done in HYPERMESH 13.0. The study investigations were carried on plates starting with three layers of the top location of 00 angle -ply laminated composite plates at the clamped boundary condition. This work also contains, a number of Finite element analyses carried out for various aspect ratios and modulus ratios to study the effect of stresses of laminated composite plates subjected to tensile load. The HYPERMESH results showed, on the stresses. The effect of increasing the aspect ratio is to decrease the stresses. The composite plate has been analyzed various modulus ratios and their effects on stresses so as to find the optimized conditions.
