XFEM based node scheme for the frictional contact crack problem

, 2020
In this paper, based on the nodal displacement of the crack surface element, a novel node-scheme method is proposed to model the frictional contact problem in the framework of extended finite element method (XFEM).

FRICTIONAL VISCOELASTIC CONTACT

The Quarterly Journal of Mechanics and Applied Mathematics, 1986
It is shown that, in a previous treatment of this topic [the author, ibid. 32, 25-52 (1979; Zbl 0409.73093)], the expression used for the coefficient of hysteretic friction was incomplete. Corrected expressions for this quantity are derived from a treatment of the problem which is more general, and in some respects more compact and elegant, than the ...

Frictional Heating of Elliptic Contacts

1994
Wherever friction occurs mechanical energy is transformed into heat. The maximum surface temperature associated with this heat generation can have an important influence on the tribological behaviour of the mating components. For band contacts and circular contacts this temperature has already been studied extensively.

Contact Mechanics: Friction and Wear

1998
Contact mechanics describes the stresses and the deformations in the neighbourhood of the contact between two pressed bodies. The following examples are given: concentrated and distributed normal and tangential loads, point load, pressure on a circular surface, hertzian contact for normal and tangential loadings.

Contact - Friction of Fuzzy Type. Contact - Friction of Fractal Type

1995
The aim of this paper is to introduce fuzzy and fractal friction laws. Fuzzy superpotential laws were first considered by the second author in Panagiotopoulos (1993). The phenomenon is described in terms of a nonconvex superpotential which is appropriately defined and a hemivariational inequality is obtained.

An unbiased Nitsche’s approximation of the frictional contact between two elastic structures

Numerische Mathematik, 2018
Most of the numerical methods dedicated to the contact problem involving two elastic bodies are based on the master/slave paradigm. It results in important detection difficulties in the case of self-contact and multi-body contact, where it may be ...

Friction in an elastohydrodynamic contact

Fluid Dynamics, 1976
The problem of the movement of a fluid in an elastohydrodynamic contact is examined in cases of high pressures, high displacement velocities, and low characteristic times, taking into account the nonlinear properties of the fluid — dependence of viscosity on pressure, temperature, and displacement velocity. Simple asymptotic formulas are obtained.

Dynamic frictional contact problems involving elastic coatings

Tribology International, 2018
This paper presents a general theory of dynamic frictional contact of elastic coatings pressed against by a rigid punch moving with a constant speed. Governing equations of elastodynamics are solved by applying Galilean and Fourier transformations.
