2. Benchmark solution

2.1. Calculation method

The reference solution comes from results obtained by averaging on other calculation codes [bib1].

2.2. Reference quantities and results

Tangential displacements (according to \(x\)) at points \(ABCDE\) of the contact surface (external reference).

Contact status, game and contact reaction at point \(R\) for some models (non-regression).

Contact pressures at points \(ABCDE\) of the contact surface for wear models (non-regression).

2.3. Uncertainties about the solution

Important (code average).
