I'm reading the book "Microcontiuum Field Theories I: Foundations and Solids". I got some basic idea of microcontiuum theory from the book, but the book provides little illustration on the application of these theories.
So I wonder:
What are the applications of Microcontiuum theory?
Is the theory parallel to classical continuum mechanics, so that some materials can only be modeled with microcontiuum theory instead of classical theory?
