Machine learning-informed structuro-elastoplasticity predicts ductility of disordered solids
Hongyi Xiao, Ge Zhang, Entao Yang +5
All solids yield under sufficiently high mechanical loads. Below yield, the mechanical responses of all disordered solids are nearly alike, but above yield every different disorder…
Modeling Stratified Segregation in Periodically Driven Granular Heap Flow
Hongyi Xiao, Zhekai Deng, Julio M. Ottino +2
We present a continuum approach to model segregation of size-bidisperse granular materials in unsteady bounded heap flow as a prototype for modeling segregation in other time varyi…
Structuro-elasto-plasticity (StEP) model for plasticity in disordered solids
Ge Zhang, Hongyi Xiao, Entao Yang +5
Elastoplastic lattice models for the response of solids to deformation typically incorporate structure only implicitly via a local yield strain that is assigned to each site. Howev…
Probing the Gardner transition in an active quasi-thermal pressure-controlled granular system
Hongyi Xiao, Andrea J. Liu, Douglas J. Durian
To experimentally search for signals of the Gardner transition, an active quasi-thermal granular glass is constructed using a monolayer of air-fluidized star-shaped granular partic…
Strain localization and failure of disordered particle rafts with tunable ductility during tensile deformation
Hongyi Xiao, Robert JS Ivancic, Douglas J Durian
Quasi-static tensile experiments were performed for a model disordered solid consisting of a two-dimensional raft of polydisperse floating granular particles with capillary attract…
Stagnant Zone Formation in a 2D Bed of Circular and Elongated Grains under Penetration
Matt Harrington, Hongyi Xiao, Douglas J. Durian
When a large blunt object penetrates into a granular material, the force response exhibits an initial nonlinear relationship with depth that is widely attributed to the formation o…
Asymmetric concentration dependence of segregation fluxes in granular flows
Ryan P. Jones, Austin B. Isner, Hongyi Xiao +3
We characterize the local concentration dependence of segregation velocity and segregation flux in both size and density bidisperse gravity-driven free-surface granular flows as a…
Unsteady flows and inhomogeneous packing in damp granular heap flows
Hongyi Xiao, John Hruska, Julio M. Ottino +2
We experimentally study the transition from steady flow to unsteady flow in a quasi-2D granular heap when small amounts of water are added to monodisperse glass spheres. Particles…
Transient response in granular quasi-2D bounded heap flow
Hongyi Xiao, Julio M. Ottino, Richard M. Lueptow +1
We study the transition between steady flows of non-cohesive granular materials in quasi-2D bounded heaps by suddenly changing the feed rate. In both experiments and simulations, t…
