Modelling Rock Behaviour with Linear Slip Deformation Theory

The dynamic elastic properties of rock are defined in terms of linear slip deformation theory, which is based on infinitesimal motion across weak planes being linearly related to the traction on those planes. The linear parameters governing slip on these planes though are highly non-linear functions of static stress state, and as such the theory provides a way to predict, based on a very limited set of measurements, the acoustic behavior of dry granular rock as a function of static stress.
