W. S. Blair Surv. Gen. & Appl. Rheol. iii. 31 The exceptions [to this rule] are..(c) Materials whose consistency is increased by increasing the stress (as distinct from the strain) applied to them. This phenomenon has been little studied, but may be referred to as ‘stress-dilatancy’. 1962 Proc. Royal Soc. A. 269 500 (heading) The stress-dilatancy relation for static equilibrium of an assembly of particles in contact. 1997 R. J. Wan & P. J. Guo in A. Asoaka et al. Deformation & Progressive Failure in Geomechanics 46/1 The essence of the model is the introduction of a modified stress dilatancy equation which accounts for both barotropy and pyknotropy. < as lemmas |
