The Numerical Analysis of Delamination Effects on Laminated Composites

Abstract

A composite is a structural material which consists of combining two or more constituents. Composites have lot of advantages like high stiffness-to-weight ratio, high strength-to-weight ratio, non corrosive, high fatigue-life etc. Composite materials are classified into fibrous composite materials, particulate composite materials and laminated composite materials. Laminated composite materials consist of layers of at least two different materials that are bonded together. Composite laminates are widely used in different areas due to their easy fabrication and effectiveness. Despite of their benefits composite materials have their disadvantages. Delaminations are the common damages in laminated composites. Delamination means separation of laminate at the interface between two layers. In the present study deals with the numerical analysis of delamination effects on laminated composites using ANSYS software. Various parameters such as delamination length and locations, multiple delaminations are studied.
