Shakedown in frictional contact problems

, 2007
If a linear elastic system with frictional interfaces is subjected to periodic loading, any slip which occurs generally reduces the tendency to slip during subsequent cycles and in some circumstances the system ‘shakes down’ to a state without slip.

A frictional contact problem with wear and damage for electro-viscoelastic materials [PDF]

, 2010
summary:We consider a quasistatic contact problem for an electro-viscoelastic body. The contact is frictional and bilateral with a moving rigid foundation which results in the wear of the contacting surface.

Polymer‐Redox Interactions Enhance Ferro/Ferricyanide Thermogalvanic Cells

Advanced Functional Materials, EarlyView.
Polyelectrolyte could modify the hydration structure of the redox couple in solution and improve the output performance of thermogalvanic cells, providing new fundamental insight into how electrostatic interactions can be exploited to tailor thermoelectric properties.

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 ...

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 ...

Adhesive wear and frictional behaviour of multilayered polyester composite based on betelnut fiber mats under wet contact conditions

, 2009
In the current study, a multilayered polyester composite based on betelnut fiber mats is fabricated. The adhesive wear and frictional performance of the composite was studied against a smooth stainless steel at different sliding distances (0−6.72 km) and

Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

Advanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

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

Stress-dilatancy Relation for Mohr-Coulomb Soils Following a Non-Associated Flow Rule

, 2010
Rowe\u27s stress–dilatancy relation for frictional (cohesionless) materials has been a cornerstone of soil mechanics. The original derivation of this relationship was based on incorrect energy minimisation considerations, but the relationship was proven ...
