Abstract |
In this study, microscopic deterministic and analytical contact models that take the properties of engineering surfaces into account have been developed. Geometrical characteristics of rough surfaces are deduced using the standard procedure for roughness and waviness parameters. These models allow the analyses of the asperities behaviour and real contact area. Comparison between the analytical and deterministic results shows a good correlation. The microscopic model is often enabling to simulate the real structure with complex geometry, so, a homogenisation technique has been developed. The interface of the equivalent model has been governed by the microscopic model results. Sensitivity of models responses to the random pulling of surfaces parameters has been also analysed.
