Rheology explains the meaning of the science of rheology, a science that many scientists need to use but only a few can fully grasp.

Features:

• Discusses various aspects of theoretical rheology
• Shows how particular theory, model, or equation can be used in solving different problems
• Discusses eight groups of methods, giving many choices for experimentation and guidance on where and how to use them properly
