Analysis and Design of Flight Vehicle Structures - Chapter A19
Introduction to Wing Stress Analysis by Modified Beam Theory
This document 'Analysis and Design of Flight Vehicle Structures - Chapter A19: Introduction to Wing Stress Analysis by Modified Beam Theory ' is part of the 'Analysis and Design of Flight Vehicle Structures' book by E.F. Bruhn.
Analysis and Design of Flight Vehicle Structures by E.F. Bruhn is one of the most useful Aerospace Industry and University text books ever written with the emphasis on practical application with input from both material strength and hands-on experience. It was originally published in 1965, and was revised in 1973. This book was prepared as a source of data and procedure for use in the sizing and design of both airframe and space vehicle structures and is the only book that has been widely used by the Aerospace Industry to date. The material presented herein has been compiled largely from the data of NACA reports and technical publications. Also there are chapters in this book that contain materials supplied to the author by well known flight vehicle structural experts from various universities and aerospace companies.
The book includes step-by-step analysis of flight vehicle structures with real world practical examples of numerical calculations to clarify either the method of analysis or the use of design data and/or curves to give engineers a real-world feeling of how to achieve the most efficient flight vehicle structural design. In fact engineers rarely come up empty while turning to this book for an example problem to help solve an actually design or analysis problem in flight vehicle design. It is mostly focused on metallic structural materials and includes a chapter on some selected flight vehicle metallic materials and their properties.
The book starts at the very basic Statically Determinate Structures, moving quickly on to the more specialised flight vehicle specific topics. Some of the more useful chapters include: Membrane Stress in Pressure Vessels, Elastic and Inelastic Instability of Columns and Thin Sheets, Buckling of Flat Sheets, Monocoque Cylinders and Conical Shells, Sandwich Structural Design, Welded Aircraft Structures, Fittings and Connections, Bolted and Riveted and the list goes on.
It is a widely used and highly recommended resource for both academia and industry.
