Niu M. Airframe Stress Analysis and Sizing

Adaso / Adastra Engineering Center, 2011. - 806 p. - ISBN10: 9627128082This book provides engineers with a fundamental understanding of thin sheet construction to achieve the most efficient structures.Michael Niu has once again produced a very reasonable book. This book is destined to become a standard reference and will complement the other classic in the industry very well (Bruhn's Analysis and Design of Flight Vehicle Structures). The book covers just about most topics required to perform effective practical stress analysis. Again as with Bruhn this is a bit of a cookbook, but in many instances that's what is required to design practical aerospace structures.Some of the material is a repeat of what's available in Bruhn; however, there is plenty of additional material which makes this book worth having. The big drawback of this book is that there are a lot of mistakes in the formulas, etc.
This was likely a result of trying to rush the book to print. As pointed out in the other reviews, most of the material in this book needs to be cross referenced with other books of company manuals before being used. Having said this the book can still be very useful and one needs to remember that practical stress analysis books are scarce and so Niu is to be congratulated just for trying to put something down on paper.Abbreviations, acronyms and nomenclature
