Rearrangements and Dilatancy for Sheared Dense Materials
arXiv:cond-mat/0108442 · doi:10.1103/PhysRevLett.89.195503
Abstract
Constitutive equations are proposed for dense materials, based on the identification of two types of free-volume activated rearrangements associated to shear and compaction. Two situations are studied: the case of an amorphous solid in a stress-strain test, and the case of a lubricant in tribology test. Varying parameters, strain softening, shear thinning, and stick-slip motion can be observed.
