Topological signatures of jamming in granular force networks via persistent homology
S Vishali, Abrar Naseer, Vijay Natarajan +1
Granular materials exhibit intricate force networks, often concentrated in chains rather than being uniformly distributed. These meso-scale structures are complex to characterize,…
Micromechanics of compressive and tensile forces in partially-bonded granular materials
Abrar Naseer, Karen E. Daniels, Tejas G. Murthy
In granular media, the presence of even small amounts of interparticle cohesion manifests as an increase in the bulk strength and stiffness, effects that are typically associated w…
Photoelastic Grain Solver v2.0: An updated tool for analysis of force measurements in granular materials
Carmen L. Lee, Lori McCabe, Ben McMillan +6
Photoelastic force imaging is an experimental technique whereby a birefringent granular material is imaged with a polariscope to characterize the internal stress state of a granula…
Extracting Contact Forces in Cohesive Granular Ensembles
Abrar Naseer, Karen E. Daniels, Tejas G. Murthy
Interparticle cohesion is prevalent in stored powders, geological formations, and infrastructure engineering, yet a comprehensive understanding of the effects of its micro-mechanic…
Multi-scale Cycle Tracking in Dynamic Planar Graphs
Farhan Rasheed, Abrar Naseer, Emma Nilsson +2
This paper presents a nested tracking framework for analyzing cycles in 2D force networks within granular materials. These materials are composed of interacting particles, whose in…
