Numerical prediction of fretting contact durability using energy wear approach: Optimisation of finite-element model

Fretting fatigue – Experimental and numerical approaches

“…In the last decade, some authors have been trying to adopt a simulation procedure including surface wear based on the Archard formula [8] or the dissipated energy concept [11]. However, incremental wear estimation together with damage cumulation is still not feasible for real structures.…”

On the Thermodynamics of Friction and Wear―A Review

“…Extensive studies have been reported by Fouvry and collaborators [18][19][20][21][22][23][24] who analyzed the fretting phenomenon of contacting surfaces with particular attention to coated surfaces, on the basis of energy dissipation in a fretting contact. They argue [18] that energy dissipation is the primary parameter needed to quantify damage.…”

“…In present analysis, λ can be sliding velocity, u, normal load, N, or temperature T. Using Equation (24) and assuming that thermodynamic flow, J, and force, X, depend on the variable λ, Equation (22) can be written as:…”

A combined wear-fatigue design methodology for fretting in the pressure armour layer of flexible marine risers

“…To reduce the computational time for fretting wear simulations, a cycle jumping technique [22,43] was employed, where it is assumed that the contact pressure and slip distributions remain constant over ΔN cycles. Therefore Equation ((3) becomes:…”
