Establish free-body diagrams (FBDs). Sum all forces and moments to ensure external loads match internal reactions.
Some of the key topics covered in the book include:
In modern engineering work, classical hand calculations from Curtis are used to validate computer models. Engineers use Finite Element Analysis (FEA) software for complex geometry. However, they rely on closed-form solutions from textbooks to perform sanity checks on the FEA results.

, which is essential for determining the limit loads an aircraft can handle during maneuvers or gusts. Margin of Safety:
Howard D. Curtis’s Fundamentals of Aircraft Structural Analysis remains an essential guide for navigating the complex physics of airframe design. By systematically working through its chapters—from basic stress tensors to thin-walled shear flow and global stiffness matrices—aspiring aerospace professionals build the foundational intuition required to design the next generation of safe, high-performance aircraft.
Curtis’s text establishes a rigorous foundation by translating general engineering mechanics into aerospace-specific applications. Aircraft structures must withstand immense aerodynamic and inertial forces while remaining incredibly lightweight, necessitating specific analytical approaches. 1.
