The need for building robots with soft materials emerged recently from considerations of the
limitations of service robots in negotiating natural environments, from observation of the role …

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

Soft, disordered, micro-structured materials are ubiquitous in nature and industry, and are
different from ordinary fluids or solids, with unusual, interesting static and flow properties …

Estimates of the onset of sediment motion are integral for flood protection and river
management but are often highly inaccurate. The critical shear stress (τ* c) for grain …

We numerically study the structure of the interactions occurring in three-dimensional
systems of hard spheres at jamming, focusing on the large-scale behavior. Given the …

We study the rheological behavior of colloidal suspensions composed of soft sub-micron-
size hydrogel particles across the liquid–solid transition. The measured stress and strain …

Strain-controlled isotropic compression gives rise to jammed packings of repulsive,
frictionless disks with either positive or negative global shear moduli. We carry out …

We introduce a novel numerical method for the simulation of soft granular materials, in which
the particles can undergo large strains under load without rupture. The proposed approach …

Efficient selections of particle-scale contact parameters in discrete element modelling
remain an open question. The aim of this study is to provide a hybrid calibration framework …

The third body approach deals with friction as a problem of third body rheology. Using a
multibody meshfree model, we report influence of cohesion on third body rheology and …
