Aircraft Structures for Engineering Students, Fifth Edition, is the leading self-contained aircraft structures course text. It covers all fundamental subjects, including elasticity, structural analysis, airworthiness, and aeroelasticity. The author has revised and updated the text throughout and added new examples and exercises using Matlab. Additional worked examples make the text even more accessible by showing the application of concepts to airframe structures. The text is designed for undergraduate and postgraduate students of aerospace and aeronautical engineering. It is also suitable for professional development and training courses.

Key Features

  • New worked examples throughout the text aid understanding and relate concepts to real world applications
  • Matlab examples and exercises added throughout to support use of computational tools in analysis and design
  • An extensive aircraft design project case study shows the application of the major techniques in the book


Undergraduate and postgraduate students of aerospace and aeronautical engineering. Also suitable for professional development and training courses
