Abstract: This paper investigates the evolution of the fabric for different contact networks (i.e., the strong, weak, and overall contact networks) in granular material. Two-dimensional tests along proportional strain paths and ...

Abstract: The elastic modulus of a granular assembly composed of spherical particles in Hertzian contact usually has a scaling law with the mean effective pressure p as K∼G∼p1/3. Laboratory test results, however, reveal that the ...
