Design Equations and Criteria of Orthotropic Composite Panels

Abstract

The U.S. Navy is currently pursuing lightweight material options for shipboard structural applications, including hull, topside and mast structures. It is necessary to develop preliminary design criteria and methods to assess structures before the development of detailed finite element models. The design equation and criteria presented in this report are for simply-supported orthotropic plate typically used in composite ship structures. The design equations presented provide orthotropic plate solutions for principal use in code development. In addition, the method could extend to overall ship structural design, for scanting design, or for input into an overall design program. This document provides design equations and criteria for simply-supported orthotropic plates in the context of the design of composite hull and topside structures. It identifies ship structural loads, structural design criteria, and design equations for solid, sandwich and hat-stiffened panels, as well as girders and frames.
