Combining the Cosserat continuum with Breakage mechanics in a consistent thermodynamic way, offers substantial benefits to our capacity to model granular physics by accounting for both the entire grain size distribution, and its evolution. We provide an upscaling procedure that introduces material parameters accounting for the contribution of an evolving internal length representing the statisticsContinue reading “A Cosserat Breakage Mechanics model for brittle granular media”

Single particle breakage under uniaxial compression test
Single Leighton Buzzard sand particles were compressed uniaxially and two primary breakage modes were proposed: splitting and explosive. In the splitting mode, the particle breaks into two or three large pieces without the creation of numerous small fragments. In terms of force-displacement curve, it tends to be almost linear while the crack initiates and propagatesContinue reading “Single particle breakage under uniaxial compression test”
