Standard Methods for Aerospace Stress Analysis

Create safer, more reliable planes with this crucial guide

Aerospace Stress Analysis is the field of research and engineering that evaluates stresses and strains on aerospace structures. By analyzing how different materials and components respond to forces, it helps aerospace engineers build for structural integrity and safety. Combining mathematical and computational models with experimental techniques, it's a crucial component of developing viable aerospace technologies.

Standard Methods for Aerospace Stress Analysis offers a thorough, practical overview of the structural and stress analysis of both principal and secondary aircraft structures. It covers both fundamental concepts and advanced computational methods, along with key applications. With coverage of both interior and exterior structures, it's a one-stop shop for all major aspects of stress analysis.

Standard Methods for Aerospace Stress Analysis features:

• Step-by-step examples for every aircraft section
• Detailed discussion of methods including Finite Element Analysis
• An overview of key information on static, fatigue, damage tolerance, buckling, and more

Standard Methods for Aerospace Stress Analysis is ideal for professional mechanical and aerospace engineers working in the aircraft or space industries, as well as students in the field.
