Collective Asperity Dynamics and the Origin of Static Friction
Kasra Farain, Daniel Bonn
Solid interfaces resist sliding up to a threshold shear force, called static friction, beyond which they start moving and their resistance drops to the kinetic friction. Static fri…
Anomalous Creep as a Precursor to Failure in Granular Materials
Kasra Farain, Daniel Bonn
Granular materials, composed of discrete solid grains, can be modeled as simple mechanical systems. However, these materials can undergo spontaneous slow deformation, or creep, eve…
Structural Relaxation in Simple Yield Stress Materials Influences Their Rheology
Kasra Farain, Daniel Bonn
Simple yield stress materials are composed of soft particles, bubbles, or droplets with purely repulsive forces. The constituent elements are typically too large to undergo thermal…
Ductile-to-brittle transition and yielding in soft amorphous materials: perspectives and open questions
Thibaut Divoux, Elisabeth Agoritsas, Stefano Aime +37
Soft amorphous materials are viscoelastic solids ubiquitously found around us, from clays and cementitious pastes to emulsions and physical gels encountered in food or biomedical e…
Thermal properties of athermal granular materials
Kasra Farain, Daniel Bonn
Dry granular materials consist of a vast ensemble of discrete solid particles, interacting through complex frictional forces at the contact points. The particles are so large that…
Perturbation-induced granular fluidization as a model for remote earthquake triggering
Kasra Farain, Daniel Bonn
Studying the effect of mechanical perturbations on granular systems is crucial for understanding soil stability, avalanches, and earthquakes. We investigate a granular system as a…
