Cascade Crack in Chain of Beads
Meysam Bagheri, Thorsten Pöschel
We consider a homogeneous chain of spheres linked by liquid bridges under tension. The rupture of a single liquid bridge leads to a fragmentation cascade driven by the inverse rela…
Comparison of bulk properties of wet granular materials using different capillary force approximations
Meysam Bagheri, Sudeshna Roy, Thorsten Pöschel
We perform Discrete Element Method simulations of wet granular matter in a split-bottom shear cell. To calculate the capillary forces from the liquid bridges between the grains, we…
Discrete Element Simulations of particles interacting via capillary forces using MercuryDPM
Meysam Bagheri, Sudeshna Roy, Thorsten Poeschel
We present the implementation of two advanced capillary bridge approximations within the Discrete Element Method (DEM) framework of the open-source code MercuryDPM. While MercuryDP…
Approximate Expressions for the Capillary Force and the Surface Area of a Liquid Bridge between Identical Spheres
Meysam Bagheri, Sudeshna Roy, Thorsten Pöschel
We consider a liquid bridge between two identical spheres and provide approximate expressions for the capillary force and the exposed surface area of the liquid bridge as functions…
