Book Reviews of Finite Element Modeling for Stress Analysis

Book Review: Good, but Needs More Development
Summary: 4 Stars

But the book needs more development. What engineers want is a book that will give the BASIC mathematical foundations, and then get on with showing how to DO finite element analysis. That was the attempt of Adams and Askenazi's book, "Building Better Products with Finite Element Analysis", but unfortunately it came across as overly-simplified and lacking in specifics (too much fluff, and not enough meat).

In contrast, Cook zeros in on the core material without wasting words. Problem is, the material comes across in a cursory manner without the development it deserves. The author frequently broaches complex topics, and then gives insufficient discussion to clarify them. I'm sure he understands them, but the rest of us need a little more explanation, in layman's terms, with examples.

In summary, the book needs more... more real world problems; more examples on how to avoid pitfalls in applying boundary conditions; more useful discussion on contact analysis; more quantitative information on how fine to make a mesh. Sure, we all know that hex elements are better than tets, but how much better? Roughly how many hex elements per 90 degrees of arc are required to get sufficient accuracy for hex-8s, tet-4s, and tet-10s? I realize there are no exact answers to these questions, but surely there are rules of thumb that practicing engineers use, because most practicing engineers don't have time to run 10 different mesh refinements and do a convergence analysis.

I apologize if I sound like I'm venting, which I am, but if you don't find any of this helpful, just remember what you paid for it.
