Analysis of friction among grain particles in warehousebased on finite element method
Liang you shipin ke-ji, 2019 In order to investigate the stress distribution between grain particles and the distribution of relative static friction between grain particles and silo walls, the ideal elastic-plastic constitutive relationship and Drucker-prager yield criterion were ...

Quasi-static contact problem with finitely many degrees of freedom and dry friction [PDF]
, 2008 A quasi-static contact problem is considered for a non-linear elastic system with finitely many degrees of freedom. Coulomb's law is used to model friction and the friction coefficient may be anisotropic and may vary along the surface of the rigid ...

Model for the static friction coefficient in a full stick elastic-plastic coated spherical contact
Friction, 2018 Finite element analysis is used to investigate an elastic-plastic coated spherical contact in full stick contact condition under combined normal and tangential loading. Sliding inception is associated with a loss of tangential stiffness.

Analysis of a dry friction problem under small displacements: application to a bolted joint [PDF]
, 2003 This study presents an analysis of the problem of macroscopic contact of steel upon steel with dry friction, in the specific case of a bolted joint. The configurations of these types of joints result in very small displacements and interface sliding ...

Static friction in oil lubricated cold forming processes
, 2022 Friction is one of the variables that have a far-reaching influence on forming processes. In the past, less attention was paid to static friction than to sliding friction in forming processes.

Measurement Method of Static Friction by a Piezoelectric Impact Drive Mechanism
Tribology Online, 2008 The coefficient of static friction is one of the basic factors of actuator performance; it influences the operational characteristics of actuators. In this present study we focus on the dependence of the coefficient of static friction on the time of ...
