Bartlett, 2011 The angle of dilationcontrols an amount of plastic volumetric strain developed during plastic shearing and is assumed constant during plastic yielding. The value of =0 corresponds to the volume preserving deformation while in (regardless of overconsolidated layers) are characterized by a very low amount of dilation ( 0). As for sands, the angle of dilation depends on the angle of internal friction. For non-cohesive soils (sand, gravel) with the angle of internal friction >30 the value of dilation angle can be estimated as = -30.
