Reddit reviews Analysis of Aircraft Structures: An Introduction (Cambridge Aerospace Series)

I'm an aerospace engineering grad student studying solids/structures. My experience has been that at least our background courses like linear elasticity, beam theory, fatigue, fracture are all fundamental enough that they don't exclude any non-aero students. The more advanced courses like fracture mechanics are actually cross-listed with the civil department so we're all mixed in the same class. Research-wise for us, it's just the application happens to be aerospace so that dictates material choices, loading scenarios, etc. There are more specialized topics like aeroelasticity that you could look into books/courses for. I don't know what things would be like in industry but I think a structural engineering concentration within civil engineering will likely provide you with the fundamental knowledge of mechanics that you'd need for aerospace, too.
