Cubic B-splines for Isogeometric Analysis of Laminated Composite Plates Subjected to Hygroscopic Loading Using Classical Laminated Plate Theory
Abstract: Composite laminates are inevitably used in several engineering structures due to their high strength and stiffness to weight ratio. The laminates are subjected to change in moisture content and the flexural behavior leads to change in the strength. Presence of moisutre may induce residual stresses and strains. Isogeometric analysis is a well-proven method to perform analysis of laminated composite plates. The main focus of this study is to apply isogeometric …

Robust Design of Subsonic Airfoil by Multi-Objective Six Sigma Approach
Abstract: It is well known that aerodynamic performance of a UAV is very sensitive to the wing shape and flight conditions, and inevitable uncertainties such as wing manufacturing errors and wind variations may lead to drastic deterioration in its aerodynamic performance. In the UAV wing design, therefore, it is required not to use the conventional design optimization approach considering only optimality of performance at the design point, but to use the …

Design and Analysis of a Metal Lined Composite Overwrapped Pressure Vessel
Abstract: This study presents a comprehensive investigation into the mechanical behavior of a metal lined composite overwrapped pressure vessel, designed for high-pressure storage applications. The design approach is dependent upon fiber material constants and dome shape factor. The study begins with obtaining dome coordinates and maintaining winding angles according to a geodesic path equation. Thickness estimation for the portion of cylindrical shell and domes are determined through netting analysis and cubic …
