Aging and configurational memories at rough frictional interfaces
Kasra Farain, Daniel Bonn
Frictional interfaces retain distinct memories of how they were sheared and how long they have rested, yet rate-and-state descriptions typically compress these histories into a sin…
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…
Predicting frictional ageing from bulk relaxation measurements
Kasra Farain, Daniel Bonn
The coefficient of static friction between solids generally depends on the time they have remained in static contact before the measurement. Such frictional aging is at the origin…
Quantitative understanding of the onset of dense granular flows
Kasra Farain, Daniel Bonn
The question when and how dense granular materials start to flow under stress, despite many industrial and geophysical applications, remains largely unresolved. We develop and test…
Non-monotonic dynamics in the onset of frictional slip
Kasra Farain, Daniel Bonn
The transition from static to dynamic friction is often described as a fracture-like instantaneous slip. However, studies on slow sliding processes aimed at understanding frictiona…
A relaxation constant in the folding of thin viscoelastic sheets
Kasra Farain
If one folds a thin viscoelastic sheet under an applied force, a line of plastic deformation is formed which shapes the sheet into an angle. We determine the parameters that define…
