Virginia Tech’s Kevin T. Crofton Department of Aerospace and Ocean Engineering and Virginia Tech Publishing are pleased to announce publication of a new open textbook by Eric Raymond Johnson, Ph.D., titled, Aerospace Structures.
Aerospace Structures (https://doi.org/10.21061/AerospaceStructures) is a 600+ page text and reference book for junior, senior, and graduate-level aerospace engineering students.
The text begins with a discussion of the aerodynamic and inertia loads acting on aircraft in symmetric flight and presents a linear theory for the statics and dynamic response of thin-walled straight bars with closed and open cross-sections. Isotropic and fiber-reinforced polymer (FRP) composite materials including temperature effects are modeled with Hooke’s law. Methods of analyses are by differential equations, Castigliano’s theorems, the direct stiffness method, the finite element method, and Lagrange’s equations. There are numerous examples for the response of axial bars, beams, coplanar trusses, coplanar frames, and coplanar curved bars. Failure initiation by the von Mises yield criterion, buckling, wing divergence, fracture, and by Puck’s criterion for FRP composites are presented in the examples.
