Dynamic frictional contact for elastic viscoplastic material

open access: yesElectronic Journal of Differential Equations, 2007
Using a general theory for evolution inclusions, existence and uniqueness theorems are obtained for weak solutions to a frictional dynamic contact problem for elastic visco-plastic material.

Review of modeling tool‒rock frictional contact with a blunt PDC cutter

open access: yesJournal of Intelligent Construction
The mechanisms of tool‒rock frictional contact are reviewed, with a focus on recent advances in numerical modeling. An idealized problem is defined for tool‒rock frictional contact with a rigid blunt tool sliding on the surface of a half-space.

整体式压力可调扭轮摩擦传动机构研究

open access: yesJixie chuandong, 2008
In traditional twist-roller frictional driving mechanism the dimensional precision of shaft and twist-roller is too high,and the contact force between the shaft and the twist-roller is tend to too great or too little,to resolve these problems,a new style

Finite elements for contact problems in two-dimensional elastodynamics [PDF]

open access: yes
A finite element approach for contact problems in two dimensional elastodynamics was proposed. Sticking, sliding, and frictional contact were taken into account.

The mechanics of delamination in fiber-reinforced composite materials. Part 1: Stress singularities and solution structure [PDF]

open access: yes
The fundamental mechanics of delamination in fiber composite laminates is studied. Mathematical formulation of the problem is based on laminate anisotropic elasticity theory and interlaminar fracture mechanics concepts.
