Frictional shear cracks

, 2002
We discuss crack propagation along the interface between two dissimilar materials. The crack edge separates two states of the interface, ``stick'' and ``slip''. In the slip region we assume that the shear stress is proportional to the sliding velocity, i.

Using the fractional interaction law to model the impact dynamics in arbitrary form of multiparticle collisions

, 2004
Using the molecular dynamics method, we examine a discrete deterministic model for the motion of spherical particles in three-dimensional space. The model takes into account multiparticle collisions in arbitrary forms.

Static Friction between Elastic Solids due to Random Asperities

, 2000
Several workers have established that the Larkin domains for two three dimensional nonmetallic elastic solids in contact with each other at a disordered interface are enormously large. This implies that there should be negligible static friction per unit

Fracture Mechanics implications for apparent static friction coefficient in contact problems involving slip-weakening laws

, 2015
We consider the effect of differing coefficients of static and dynamic friction coefficients on the behaviour of contacts involving microslip. The classic solutions of Cattaneo and Mindlin are unchanged if the transition in coefficients is abrupt, but if

Network-Configurations of Dynamic Friction Patterns

, 2012
The complex configurations of dynamic friction patterns-regarding real time contact areas- are transformed into appropriate networks. With this transformation of a system to network space, many properties can be inferred about the structure and dynamics ...

Dynamic Effects of the Underground Squat Silo during Symmetic Discharging with Different Static Friction Coefficients

Liang you shipin ke-ji
Underground squat silos can utilize shallow geothermal energy to realize natural quasi-low temperature storage to ensure the grain quality, which is a suitable warehouse for green grain storage. A combined approach of numerical simulation and theoretical

On the Normal Force and Static Friction Acting on a Rolling Ball Actuated by Internal Point Masses

, 2019
The goal of this paper is to investigate the normal and tangential forces acting at the point of contact between a horizontal surface and a rolling ball actuated by internal point masses moving in the ball's frame of reference.
