There are three central themes running throughout the presentation:
· Rocks as the prototypical material for defining a class of materials
· The PM space model as a useful theoretical construct for developing a phenomenology
· A sequence of refined analysis methods.
This suite of new methods for both recording and analyzing data is more than a single framework for interpretation, it is also a toolbox for the experimenter. A comprehensive and systematic book of utmost interest to anybody involved in non-destructive testing, civil engineering, and geophysics.
