Modeling of heterogeneous materials and media is a problem of fundamental importance to
a wide class of phenomena and systems, ranging from condensed matter physics, soft …

The simplicity of hard spheres as a model system is deceptive. Although the particles
interact solely through volume exclusion, that nevertheless suffices for a wealth of static and …

Jamming is a ubiquitous phenomenon that appears in many soft matter systems, including
granular materials, foams, colloidal suspensions, emulsions, polymers, and cells—when …

Urbanization and climate change are contributing to severe flooding globally, damaging
infrastructure, disrupting economies, and undermining human well-being. Approaches to …

The physical and mechanical performance of concrete is inherently dependent on
aggregate morphology including the general shape at coarse-scale, the local roundness at …

At large scales, particulate suspensions flow like homogeneous viscous liquids, but at the
particle scale, the role of the local heterogeneity brought by the particles cannot be …

Introducing a reduced particle stiffness in discrete element method (DEM) allows for bigger
time steps and therefore fewer total iterations in a simulation. Although this approach works …

Jamming is an athermal transition between flowing and rigid states in amorphous systems
such as granular matter, colloidal suspensions, complex fluids and cells. The jamming …

The properties of granular materials depend strongly on the shapes of their individual
constituent particles or granules. Nonetheless, incorporating the effects of non-spherical or …
