Knowledge of ignorance of such basic input as loads and stresses in practical cases may cause errors far overshadowing those introduced by shortcomings of fracture mechanics and necessary approximations; this is amply demonstrated in the text. I have presented more than three dozen hour courses on fracture mechanics and damage tolerance analysis, so that I have probably more experience in teaching the subject than anyone else.
I learned more than the students, and became cognizant of difficulties and of the real concerns in applications.

- Executive Summary!
In particular I found, how a subject should be explained to appeal to the practicing engineer to demonstrate that his practical problem can indeed be solved with engineering methods. Sufficient background is provided for an understanding of the issues, but pragamatism prevails. Mathematics cannot be avoided, but they are presented in a way that appeals to insight and intuition, in lieu of formal derivations which would show but the mathematical skill of the writer.
