Bulk Modulus along Jamming Transition Lines of Bidisperse Granular Packings
Juan C. Petit, Nishant Kumar, Stefan Luding +1
We present 3D DEM simulations of bidisperse granular packings to investigate their jamming densities, , and dimensionless bulk moduli, , as a function of the size ratio, $δ…
The influence of material properties and process parameters on the spreading process in additive manufacturing
Mohamad Yousef Shaheen, Anthony R. Thornton, Stefan Luding +1
Laser powder bed fusion (LPBF) is an additive manufacturing (AM) technology. To achieve high product quality, the powder is best spread as a uniform, dense layer. The challenge for…
Stretching the limits of dynamic and quasi-static flow testing on limestone powders
Hao Shi, Geoffroy Lumay, Stefan Luding
Powders are a special class of granular matter due to the important role of cohesive forces. The flow behavior of powders depends on the flow states and stress and is therefore dif…
Additional transition line in jammed asymmetric bidisperse granular packings
Juan C. Petit, Nishant Kumar, Stefan Luding +1
We present numerical evidence for an additional discontinuous transition inside the jammed regime for an asymmetric bidisperse granular packing upon compression. This additional tr…
Surface flow profiles for dry and wet granular materials by Particle Tracking Velocimetry; the effect of wall roughness
Sudeshna Roy, Bert J. Scheper, Harmen Polman +4
Two-dimensional Particle Tracking Velocimetry (PTV) is a promising technique to study the behaviour of granular flows. The aim is to experimentally determine the free surface width…
Transition rates for slip-avalanches in soft athermal disks under quasi-static simple shear deformations
Kuniyasu Saitoh, Norihiro Oyama, Fumiko Ogushi +1
We study slip-avalanches in two-dimensional soft athermal disks by quasi-static simulations of simple shear deformations. Sharp drops in shear stress, or slip-avalanches, are obser…
