- Abstract
Laminated composite is an emerging area of Civil Engineering. The conventional materials can be replaced with composite materials having light weight and improved strength. This study aims to perform a static analysis of laminated composite plates using a six node curved shell triangular element. The shape functions are of the second degree, which can precisely represent the variation of displacement within the element. The coding for this study is done using MATLAB®. In this study, two standard examples from the literature have been solved, - simply supported and clamped boundary conditions. The maximum central deflection for a simply supported plate carrying a uniformly distributed load using six node triangular element is 0.4449 when compared with the maximum central deflection of 0.4498 using LDT18 formulation given in the literature. The central deflections show an improved result over the existing results by many authors available in the literature. The deformed shape of the plate is presented. This study can be useful for the analysis of narrow domains where the use of quadrilateral elements is not feasible.
