The variational discrete element method developed in [28] for dynamic elasto-plastic computations is adapted to compute the deformation of elastic Cosserat materials. In addition cellwise displacement degrees freedom (dofs), rotational dofs are added. A reconstruction devised obtain P 1 non-conforming polynomials each cell and thus constant strains stresses cell. requires only usual macroscopic...

The efficiency of the simulations with discrete element method (DEM) is significantly improved using a novel computational strategy. new developed focus on platforms equipped multi-core central processing units (CPU) and general-purpose graphics (GPU). DEM calculations are performed in parallel CPU GPU pre-calculated Verlet lists posteriori analysis their consistency. operations related to sear...

The discrete element method (DEM) is usually applied in analyzing the scientifical origin/evolution of asteroids and landing/sampling regolith. In order to manage contact between non-spherical granules, Polygonal Contact Model (PCM) has been introduced into DEM method. This paper applies four different force models newly-proposed algorithm analyze their difference implication. include one linea...
