2 - Elastic Rock Rheology and Stress Concentration


Rheology is the study of flow or, more generally, the response of a material like rock to imposed stresses or strains (e.g., Johnson, 1970, pp. 13–22; Weijermars, 1997, p. 13; Karato, 2008). In this chapter we first review some aspects of experimental rock deformation that are relevant to the simplest and perhaps most widely used rheologic model for rocks, that of an elastic material. We’ll then examine the terminology of deformation and strain that flows from the corpus of laboratory studies of rock deformation.
