Good Text, Major Problems with Matlab Tools, May 3, 2007
Taken by itself, this is a good solid text on its subject matter, both during the learning process and as a later reference for a working engineer (which I am - with 35 years of experience). However, the Matlab "toolbox" is significantly flawed. First, the tools are presented as p-code, not m-scripts, and therefore serve no teaching function whatsoever, and cannot be customized by the user. There is no logical reason for this from a protection standpoint since there is no copy-protection on the disk and thus, at least physically, the files can be just as freely distributed as if they were m-scripts. Even toolboxes purchased from MathWorks generally contain most of their tools as user readable m-scripts. Because they're not user readable, and therefore not verifiable, the Matlab tools on the CD cannot be used in any quality sensitive "real-world" engineering computation. Another toolbox problem is that it is divided into chapter-related folders and tool names are repeated in different folders - requiring in many cases completely incompatible syntax for the different versions - all with the same name. If the wrong syntax is used, the routines fail cryptically, not gracefully. Finally, no help messages are built into the tools (eg. the standard Matlab syntax "help myfunction" does NOT produce any info about the "myfunction" routine - of which there may be as many incompatible versions as there are chapters). This is definitely not standard practice for Matlab toolboxes and is definitely not user friendly. The author's website does not appear - at this writing anyway - to have any updates or corrections for the toolbox routines. So if you purchase this book, do so for the book itself, not the toolboxes which seem so promising in concept.
Updating this review after a year or so, I would reduce the stars to two (if Amazon allowed this) because, due to the flaws in the Matlab tools mentioned above I have not found any real use for the tools in day to day practice.

review, January 7, 2009
Unless the author will provide the m files , the book is of very little use. To what avail to see the results if you do not know the solution?
I do not recommend the book!!!

Dr. Yang's Book on Stress, Strain and Structural Dynamics, April 24, 2005
Dr. Yang's newly released book "Stress, Strain and Structural Dynamics" contains a substantial quantity (with 960 pages) of diverse, high-quality material on strength of materials, structural mechanics, dynamics and vibrations, structural dynamics, and two-dimensional elastic continua. The integration of the development of principles, formulas and solutions with Matlab, the high-performance technical computing language, reflects the current state of engineering education, research and development. The accompanying CD-ROM contains nearly 300 self-written functions by the author, which allows the users to not only obtain the solutions but also visualize the responses instantly. Structures covered in the interactive handbook range from simple single degree of freedom system to sophisticated two-dimensional elastic continua. As a result, it is an excellent resource for undergraduate and graduate engineering students, practical engineers and researchers. It deserves a place in all academic and specialist libraries as well as engineering professionals' bookshelves.
In addition, what's nice about this book, as I recently found out, is that the author maintains a website for the book:
http://ame-www.usc.edu/books/yang-sssd/
From this website, one can get a lot of information on what this book is about, how to use the Matlab functions of the book in engineering analysis via carefully selected demo examples, technical supports, updates, and beyond. This, from a reader's viewpoint, really helps amplifying the utilities of the book.
