Existence for viscoplastic contact with Coulomb friction problems
International Journal of Mathematics and Mathematical Sciences, 2002 We present existence results in the study of nonlinear problem of frictional contact between an elastic-viscoplastic body and a rigid obstacle. We model the frictional contact both by a Tresca's friction law and a regularized Coulomb's law. We assume, in

Semi-analytical sensitivity analysis procedure for frictional contact problems
Computer Assisted Methods in Engineering and Science, 2023 Although there is a need for sensitivity analysis for frictional contact problems in many engineering fields, research work on it has rarely been reported due to the complexity of the problems.

The contact condition of viscoelastic contact problems
Journal of Physics: Conference Series, 2023 Abstract Three contact states in the viscoelastic contact deformation area between the rigid cylinder and the viscoelastic foundation are discussed based on various material mechanical properties between the rigid and the viscoelastic materials. On this basis, the relationship model between the node displacements and the node stresses in

On contact problems for nonlinear parabolic functional differential equations
Electronic Journal of Qualitative Theory of Differential Equations, 2004 The results of [3] by W. Jäger and N. Kutev on a nonlinear elliptic transmission problem are extended (in a modified way) to nonlinear parabolic problems with nonlinear and nonlocal contact conditions.

Fatigue analysis of catenary contact wires for high speed trains [PDF]
, 2011 The fatigue fracture is one of the most critical failures which may occur on the high speed network because it is undetectable and it has a huge impact on traffic disruption.
