Introduction to Aircraft Structural Analysis, Second Edition, is an essential resource for learning aircraft structural analysis. Based on the author's best-selling text Aircraft Structures for Engineering Students, this brief book covers the basics of structural analysis as applied to aircraft structures.

Coverage of elasticity, energy methods, and virtual work sets the stage for discussions of airworthiness/airframe loads and stress analysis of aircraft components. Numerous worked examples, illustrations, and sample problems show how to apply the concepts to realistic situations.

This text is designed for undergraduate and postgraduate students of aerospace and aeronautical engineering as well as for professional development and training courses.

Key Features

  • Based on the author's best-selling text Aircraft Structures for Engineering Students, this introduction covers core concepts in about 200 fewer pages than the original by removing some optional topics like structural vibrations and aeroelasticity
  • Systematic step-by-step procedures in the worked examples
  • Self-contained, with complete derivations for key equations


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