Topological constraints suppress shear localization in granular chain ensembles
Palash Sarate, Mohd. Ilyas Bhat, Tejas G. Murthy +1
Entangled granular systems exhibit mechanical rigidity and resistance to deformation, reminiscent of cohesive materials, due to their reduced degrees of freedom and contact frictio…
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…
Role of Transient Dynamics in Dripping-Jetting Transition in Newtonian Fluids
Kishorkumar Sarva, Tejas G Murthy, Gaurav Tomar
Dripping dynamics has been well studied over the past century and forms a classic example of chaotic system in physics. With an increase in the inlet flow rate, periodic droplet fo…
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…
