Contact numbers in packings of frictional cylinders [PDF]

EPJ Web of Conferences
The mechanical stability of a granular system depends on the average number of contacts Z between its particles. For most particle shapes, predicting Z as a function of the average volume fraction ϕ is complicated by the spatial correlations between ...

On slip pulses at a sheared frictional viscoelastic/ non deformable interface

, 2000
We study the possibility for a semi-infinite block of linear viscoelastic material, in homogeneous frictional contact with a non-deformable one, to slide under shear via a periodic set of ``self-healing pulses'', i.e.

Admittance Selection for Planar Force-Guided Assembly for Single-Point Contact with Friction [PDF]

, 2003
This paper identifies procedures for selecting the appropriate admittance to achieve reliable planar force-guided assembly for single-point frictional contact cases. A set of conditions that are imposed on the admittance matrix is presented.

Antiplane frictional contact of electro-viscoelastic cylinders

Electronic Journal of Differential Equations, 2007
We study a mathematical model that describes the antiplane shear deformation of a cylinder in frictional contact with a rigid foundation. The material is assumed to be electro-viscoelastic, the process is quasistatic, friction is modelled with Tresca ...

Crack-Like Processes Governing the Onset of Frictional Slip

, 2006
We perform real-time measurements of the net contact area between two blocks of like material at the onset of frictional slip. We show that the process of interface detachment, which immediately precedes the inception of frictional sliding, is governed ...

Frictional Aging of Single‐Asperity Nanoindentation Contacts in Quartz and Calcite

Geophysical Research Letters
The evolution of fault friction during the interseismic period affects the mechanics of a future earthquake on the same fault patch. Frictional aging has been previously tied to time‐dependent contact area growth through observations made on rock analogs.

A computational framework for drop time assessment of a control element assembly under fuel assembly deformations with fluid-structure interaction and frictional contact

Nuclear Engineering and Technology
This paper presents a computational framework for drop time assessment of a control element assembly (CEA) under fuel assembly (FA) deformations. The proposed framework consists of three key components: 1) finite element modeling of CEA, 2) fluid ...

Development of the high precision measurement device of static friction characteristics between surfaces at the fixed coupling section

Nihon Kikai Gakkai ronbunshu, 2019
Mechanical systems have many joints within. It is well known that the parameters such as contact stiffness, static friction coefficient, kinetic friction coefficient and attenuation coefficient affect static, kinetic, thermal and motion characteristic of
