A variational critical-state theory of friction
Mary Agajanian, Nadia Lapusta, Anna Pandolfi +1
Friction plays a fundamental role in many natural processes, including earthquakes, landslides, and volcanic eruptions. Earthquakes occur when highly compressed fault surfaces accu…
Static and sliding contact of rough surfaces: effect of asperity-scale properties and long-range elastic interactions
Srivatsan Hulikal, Nadia Lapusta, Kaushik Bhattacharya
Friction in static and sliding contact of rough surfaces is important in numerous physical phenomena. We seek to understand macroscopically observed static and sliding contact beha…
A threshold-force model for adhesion and mode I fracture
Srivatsan Hulikal, Kaushik Bhattacharya, Nadia Lapusta
We study the relation between a threshold-force based model at the microscopic scale and mode I fracture at the macroscopic scale in a system of discrete interacting springs. Speci…
Collective behavior of viscoelastic asperities as a model for static and kinetic friction
Srivatsan Hulikal, Kaushik Bhattacharya, Nadia Lapusta
We propose a statistical model for static and sliding friction between rough surfaces. Approximating the contact between rough surfaces by the contact of an ensemble of one-dimensi…
