Force Mobilization and Generalized Isostaticity in Jammed Packings of Frictional Grains [PDF]
, 2006 We show that in slowly generated 2d packings of frictional spheres, a significant fraction of the friction forces lies at the Coulomb threshold - for small pressure p and friction coefficient mu, about half of the contacts. Interpreting these contacts as

Study of Frictional Effects of Granite Subjected to Quasi-Static Contact Loading
Lubricants, 2020 The rock fragmentation response to drilling, in particular percussive drilling, is important in order to improve the efficiency of such an operation. The resulting problem includes spherical contact between the drill bit and the material and therefore, a

A microscopic theory for discontinuous shear thickening of frictional granular materials [PDF]
, 2017 We extend a recent theory for the rheology of frictionless granular materials [K. Suzuki and H. Hayakawa, Phys. Rev. Lett. 2015, 115, 098001] to the case of frictional disks in two dimensions.

Estimation of real contact area during sliding friction from interface temperature
AIP Advances, 2016 Frictional heat is one of the most important topics in tribological research. The real contact area of the frictional pair plays a significant role in accurately estimating the interface temperature, which is closely related to the frictional heat ...

Estimation of the normal contact stiffness for frictional interface in sticking and sliding conditions [PDF]
, 2019 Modeling of frictional contact systems with high accuracy needs the knowledge of several contact parameters, which are mainly related to the local phenomena at the contact interfaces and affect the complex dynamics of mechanical systems in a prominent ...

Predicting frictional aging from bulk relaxation measurements
Nature Communications, 2023 The coefficient of static friction between solids normally increases with the time they have remained in static contact before the measurement. This phenomenon, known as frictional aging, is at the origin of the difference between static and dynamic ...

Static and sliding contact of rough surfaces: effect of asperity-scale properties and long-range elastic interactions [PDF]
, 2018 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 behavior as the collective response of a large number of microscopic ...

Rothe method and numerical analysis for history-dependent hemivariational inequalities with applications to contact mechanics [PDF]
, 2019 In this paper an abstract evolutionary hemivariational inequality with a history-dependent operator is studied. First, a result on its unique solvability and solution regularity is proved by applying the Rothe method.
