Also, some commercial software is developed based on these theories like ABAQUS, ANSYS and NASTRAN to study finite element analysis of laminated composite shell structures. The complexity arise due to anisotropic nature and geometry of laminated composite shell panel requires in depth knowledge of various theories as per the change of aspect ratios like Classical Lamination Theory (CLT), First order Shear Deformation Theory (FSDT) and Higher order Shear Deformation Theory (HSDT) and available in wide range of literature. For the accurate life prediction of these structures and extracting maximum available strength due to safety concerns, highly economic stress computation models are a need of today’s mechanical engineering design community. The use of laminated composite materials in the various structural applications has resulted in a significant increase in payload, weight reduction, speed, maneuverability and durability. Composite shell structures are widely used in aerospace components (tails, wings, fuselages, propellers), space, boat and scull hulls, bicycle frames, racing car bodies and military applications. The popularity of composite material shell panel is increasing day-by-day due to its light weight, high stiffness to weight ratio and excellent structural tailoring capabilities. As student version of ABAQUS is used to evaluate the results, it has reduced computational efforts and computational cost.Ĭomposite laminates are an assembly of layers of fibrous composite materials which can be stacked together to provide required engineering properties such as elastic moduli, Poison’s ratio, including in-plane stiffness, bending stiffness, strength, and coefficient of thermal expansion. The validation study shows good agreement between present results and existing results.

The results obtained using present finite element model is compared with the results of various literature for ensuring accuracy, efficacy and economy. The different loading conditions used are sinusoidal loading and uniformly distributed loading. 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 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 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. SNIP takes into account characteristics of the source's subject field, which is the set of documents citing that source. It helps you make a direct comparison of sources in different subject fields. SNIP measures a source’s contextual citation impact by weighting citations based on the total number of citations in a subject field. Source Normalized Impact per Paper (SNIP) 2020: 0.333 ℹ Source Normalized Impact per Paper(SNIP): SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is. It is based on the idea that 'all citations are not created equal'. The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. SCImago Journal Rank (SJR) 2020: 0.153 ℹ SCImago Journal Rank (SJR): CiteScore is the number of citations received by a journal in one year to documents published in the three previous years, divided by the number of documents indexed in Scopus published in those same three years.
