Loading-unloading contact law for micro-crystalline cellulose particles under large deformations
Yasasvi Bommireddy, Ankit Agarwal, Vikas Yettella +2
A semi-empirical mechanistic contact law for micro-crystalline cellulose (Avicel PH-200) particles is proposed and characterized experimentally using force-displacement curves obta…
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…
Statistical characterization of microstructure evolution during compaction of granular systems composed of spheres with hardening plastic behavior
Marcial Gonzalez, Payam Poorsolhjouy, Alexander Thomas +2
An extensive numerical campaign of particle mechanics calculations that predict microstructure formation and evolution during die compaction, up to relative densities close to one,…
Quantification of lubrication and particle size distribution effects on tensile strength and stiffness of tablets
Sonia M. Razavi, Marcial Gonzalez, Alberto M. Cuitiño
We adopt a Quality by Design (QbD) paradigm to better control the mechanical properties of tablets. To this end, the effect of particle size distribution, lubricant concentration,…
