Title: Dynamic Mechanical Analysis: A Practical Introduction Author(s): Kevin P. Menard Pages: 224 Publisher: CRC; 1 edition Publication date: 1999 Language: English Format: PDF ISBN-10: 0849386888 ISBN-13: Description: Although dynamical mechanical analysis or spectroscopy has left the domain of the rheologist and has become a prevalent tool in the analytical laboratory, it is still common to hear, "What is DMA, and what will it tell me?" or "I think I could use a DMA, but I cannot justify its cost." Previously, the novice in the field had to sort through texts on thermal analysis, rheology, and materials science just to find basic information - until now. This book provides the chemist, chemical engineer, or materials scientist with a starting point to understand the applications of dynamic mechanical analysis, its workings, and its advantages and limitations. Discussions include: rheological concepts stress-strain data handling experimental techniques and considerations test methods, such as frequency sweeps and time-temperature curves data analysis
Review
The author of this book has taught many short courses on DMA and this shows in his bookThis reviewer found the last chapter, on the section on the application of DMA to real problems to be very usefulThis book should be quite useful to someone who is just beginning to do thermal methods and wants to include DMA among the methods used.

it is also a practical book for engineers and scientists already working in industry.
