Hi, I am a student pursuing an MS in Aerospace Engineering with a concentration in Aerospace Structures. I am currently taking a course in Stability of Structures. The "required" textbook is Guide to Stability Design Criteria for Metal Structures (ISBN 0471127426), and the other recommended text is Stability Analysis and Design of Structures (ISBN 3540207848). Unfortunately, the first textbook is rather expensive, and the second seemed to have numerous grammatical and syntax errors in the first chapter, so I returned it (from the library). My question is, are there other reputable books out there that cover this material and that wouldn't break the bank? Also, I am taking another course in Creep, and the "required" text is $230 (Fundamentals of Creep in Metals and Alloys by Kassner). Are there other cheaper books on Creep out there? The thing is, both of these courses don't actually require the textbooks. I can't justify spending so much money on these books, yet I want to have a reference book or some resources to add to the course material. If you can recommend any for either of these courses, I would be grateful. Thanks!
