Dilatancy and the state parameter

This chapter covers the experimental evidence and historical basis for state parameter and stress-dilatancy, without straying into too much theory. As such, this is needed background information to understand the material presented in Chapters 6 and 7 about static and cyclic liquefaction behaviour, although Sections 2.7 and 2.8 could be skipped if less interested in generalized (non-triaxial) stress conditions and the ‚ner details of stress-dilatancy.
