Abstract EN
This paper presents numerical simulations of high-pressure biaxial tests on breakable granular soils with the discrete element method.
The 2D setting is more economic in terms of computational cost, which allows simulation with a larger number of particles with a wider size distribution.
The results of breakable and unbreakable agglomerates show that particle breakage has a significant influence on the macro- and micromechanical behaviors of the assembly.
Higher confining pressure and larger axial strain result in the variation of particle grading and agglomerate numbers.
The evolution of bond breakage during shearing makes it possible to trace the failure process and breakage mechanism at the microlevel.
The breakage energy is found to account for a small fraction of total energy input compared with friction energy.
A hyperbolic correlation between relative particle breakage and total energy input per unit volume was established regardless of the influence of confining pressure.
