A fast and efficient contact algorithm for fretting problems applied to fretting modes I, II and III

Numerical tribology of a dry contact

“…From a pragmatic point of view, it is also the key issue of many industrial problems (mechanism lifetime [1,2,3], different types of wear [4,5], brake squeal noise [6], vibration and noise reduction [7],etc.) and economic challenges (energetic expense, warming, etc.).…”

“…In such cases computing-time becomes one of the main constraints, forcing researchers to develop simplified models of both the dynamic behaviour of system components and contact stresses. These approaches have become efficient tools for solving well-defined problems more than general tools for understanding contact problems [1,49], because the phenomena and the scales of the mechanism and the contact are completely uncoupled.…”

“…SA models have been used for understanding wear phenomena like fretting [1,50], in simplified elasto-plastic and wear models [49]. Other researchers have developed semi-analytical methods for modelling ball bearing behaviour [2,51,3], by simplifying the interaction between the bearing elements with visco-elastic contact laws.…”

“…The literature on semi-analytical models is extremely rich and is growing rapidly every year, with specific branches that each deal with particular issues, thus it is not possible to give a complete overview of existing works and those readers interested should refer to more detailed reviews that deal with specific applications. Nevertheless, it is worth mentioning the works of Nélias [52,1,49] concerning dry contact problems and the works of Wensing [7,3] dealing with lubrificated contact problems.…”

Numerical Simulation of Slip-Stick Elastic Contact

“…Gallego, Nélias, and Deyber (Gallego et al, 2010) applied numerical analysis in an incremental approach to study different fretting modes, and concluded that assumptions adopted in existing analytical models lead to arguably inaccurate results. It is asserted in (Gallego et al, 2010) that, due to irreversibility of friction, which is a dissipative process, loading history should be considered although a purely elastic contact analysis is intended.…”
