Modeling granular material segregation using a combined finite element method and advection-diffusion-segregation equation model
Yu Liu, Marcial Gonzalez, Carl Wassgren
A two-dimensional, transient, multi-scale modeling approach is presented for predicting the magnitude and rate of percolation segregation for binary mixtures of granular material i…
Contact radius and curvature corrections to the nonlocal contact formulation accounting for multi-particle interactions in elastic confined granular systems
Ankit Agarwal, Marcial Gonzalez
We present contact radius and curvature corrections to the nonlocal contact formulation that take into account multi-particle interactions in elastic confined granular systems. The…
Generalized loading-unloading contact laws for elasto-plastic spheres with bonding strength
Marcial Gonzalez
We present generalized loading-unloading contact laws for elasto-plastic spheres with bonding strength. The proposed mechanistic contact laws are continuous at the onset of unloadi…
Connecting discrete particle mechanics to continuum granular micromechanics: Anisotropic continuum properties under compaction
Payam Poorsolhjouy, Marcial Gonzalez
A systematic and mechanistic connection between granular materials' macroscopic and grain level behaviors is developed for monodisperse systems of spherical elastic particles under…
Modeling granular material blending in a rotating drum using a finite element method and advection-diffusion equation multi-scale model
Yu Liu, Marcial Gonzalez, Carl Wassgren
A multi-scale model is presented for predicting the magnitude and rate of powder blending in a rotating drum blender. The model combines particle diffusion coefficient correlations…
Microstructure evolution of compressible granular systems under large deformations
Marcial Gonzalez, Alberto M. Cuitino
We report three-dimensional particle mechanics static calculations that predict the microstructure evolution during die-compaction of elastic spherical particles up to relative den…
A nonlocal contact formulation for confined granular systems
Marcial Gonzalez, Alberto Cuitino
We present a nonlocal formulation of contact mechanics that accounts for the interplay of deformations due to multiple contact forces acting on a single particle. The analytical fo…
