Non-local physics-informed neural networks for forward and inverse solutions of granular flows
Saghar Zolfaghari, Safa Jamali
Dense granular flows exhibit nonlocal effects due to stress transmission in microplastic events, especially in quasi-static or slowly sheared regions. Hence, traditional local rheo…
Mechanistic framework for reduced-order models in soft materials: Application to three-dimensional granular intrusion
Shashank Agarwal, Daniel I Goldman, Ken Kamrin
Soft materials often display complex behaviors that transition through apparent solid- and fluid-like regimes. While a growing number of microscale simulation methods exist for the…
Modeling silo clogging with nonlocal granular rheology
Sachith Dunatunga, Ken Kamrin
Granular flow in a silo demonstrates multiple nonlocal rheological phenomena due to the finite size of grains. We solve the Nonlocal Granular Fluidity (NGF) continuum model in quas…
Interplay between hysteresis and nonlocality during onset and arrest of flow in granular materials
Saviz Mowlavi, Ken Kamrin
The jamming transition in granular materials is well-known for exhibiting hysteresis, wherein the level of shear stress required to trigger flow is larger than that below which flo…
Efficacy of simple continuum models for diverse granular intrusions
Shashank Agarwal, Andras Karsai, Daniel I Goldman +1
Granular intrusion is commonly observed in natural and human-made settings. Unlike typical solids and fluids, granular media can simultaneously display fluid-like and solid-like ch…
Contact model for elastically anisotropic bodies and efficient implementation into the discrete-element method
Saviz Mowlavi, Ken Kamrin
We introduce a contact law for the normal force generated between two contacting, elastically anisotropic bodies of arbitrary geometry. The only requirement is that their surfaces…
