In my 16 years in the Aerospace Industry I have rarely come across a more quoted or well known text with the possible exception of Roark’s Formulas for Stress and Strain. Bruhn is the basis for most Aerospace company strength manuals. It is truly the Bible of flight vehicle analysis.
However, there is no index, only a cursory table of contents. A very good reference for a great deal of practical formulas but abrupt on theoretical explanation in most cases. Many example problems but again very abrupt on explanation. Could have better illustrations.
For all of the above reasons Bruhn gets high marks as a reference but as a text for learning it is lacking; even for someone with a background and education in basic stress analysis. It is still one of the most comprehensive and practical aircraft structural text around and still a must read for any flight vehicle structural engineer.
