Study of Frictional Effects of Granite Subjected to Quasi-Static Contact Loading
Lubricants, 2020 The rock fragmentation response to drilling, in particular percussive drilling, is important in order to improve the efficiency of such an operation. The resulting problem includes spherical contact between the drill bit and the material and therefore, a

A class of dynamic frictional contact problems governed by a system of hemivariational inequalities in thermoviscoelasticity [PDF]
, 2019 In this paper we prove the existence and uniqueness of the weak solution for a dynamic thermoviscoelastic problem which describes frictional contact between a body and a foundation.

Predicting frictional aging from bulk relaxation measurements
Nature Communications, 2023 The coefficient of static friction between solids normally increases with the time they have remained in static contact before the measurement. This phenomenon, known as frictional aging, is at the origin of the difference between static and dynamic ...

A Hybrid Material Point Method for Frictional Contact with Diverse Materials
PACMCGIT, 2019 We present a new hybrid Lagrangian Material Point Method for simulating elastic objects like hair, rubber, and soft tissues that utilizes a Lagrangian mesh for internal force computation and an Eulerian mesh for self collision as well as coupling with ...

Formulae for frictional resistance considering mud thixotropy and pipe-soil contact characteristics
Yantu gongcheng xuebao, 2017 The jacking force is the crucial parameter for the design and construction of pipe jacking projects. It is controlled by the lateral frictional resistance of pipe jacking and affected by the characteristics of pipe-soil contact and pipe-mud contact.

Journal of Manufacturing and Materials Processing, 2020 The tribological effect of cutting fluids in the machining processes to reduce the friction in the cutting zone is still widely unknown. Most test benches and procedures do not represent the contact conditions of machining processes adequately ...

Contact Hamiltonian Description of 1D Frictional Systems
Communications in Advanced Mathematical Sciences, 2021 In this paper, we consider contact Hamiltonian description of 1D frictional dynamics with no conserved force. Friction forces that are monomials of velocity, and sum of two monomials are considered.

Contact problems with friction: models and simulations [PDF]
Simulation Modelling Practice and Theory, 2003 This article deals with the modeling and the numerical simulation of contact and friction problems. Some friction formulations are proposed and numerical methods of resolution by finite elements are presented. Two methods are more particularly developed.
