The book is designed for use in junior/senior level undergraduate courses, as well as, introductory graduate courses in Experimental Stress Analysis offered in ME, CE, Aerospace Departments.

The authors realized that there are currently no texts in the marketplace that include sufficient solved examples, along with the ability to cover theories of experimental technique, in such a way as to promote self-teaching by the student. The authors' objective is to allow the student to review the materials before stepping into a laboratory situation. Chapters are written in a very concise, easily understandable manner and features the inclusion of ample solved equations, designed to test the students understanding of learned topics.
