"WebKeywords: granular materials; sandpiles; stress propagation; fragile matter 1. Introduction Recently, a new strategy for the modelling of stress propagation in static cohesionless granular media was developed (Bouchaud et al. 1995; Wittmer et al. 1996, 1997a;b). The medium is viewed as an assembly of rigid particles held up by friction. The " - Stresses in wedges of cohesionless

WebAbstract: Cohesionless wedges formed by free discharge at the apex exist completely in the active critical state. With active failure movement, sections only of the wedge may be in … Webslope, are relatively small. The stress state of a two dimensional critical wedge is perturbed by admitting a small lateral shear, which is accommodated (to maintain criticality) by a reduction in the dominant normal compressive stress. Cohesionless cases are further simplified with Taylor se- ries expansions in the topographic slope.
