Computationally efficient procedure for stress analysis of laminated composite shell subjected to different loading using abaqus software

Abstract

The purpose of this study is to develop finite element model for accurate estimation of deflection and stresses of a laminated shell panel using student version of commercial software ABAQUS. The results are obtained in terms of stress and deflection of laminated composite shell for different lamination scheme, lamination type, boundary conditions, aspect ratios, loading conditions and orthotropic ratios. The various boundary conditions used in the present analysis are clamped-clamped (CCCC), hinged-hinged (HHHH), clamped-hinged (CHCH), clamped-free (CFCF) and simply supported (SSSS). The different loading conditions used are sinusoidal loading and uniformly distributed loading. The results obtained using present finite element model is compared with the results of various literature for ensuring accuracy, efficacy and economy. The validation study shows good agreement between present results and existing results. As student version of ABAQUS is used to evaluate the results, it has reduced computational efforts and computational cost.
