Abstract: The current paper analyses the complexity and precision of FEM calculations in 2 dimensional solid mechanics. The work shows that both grid refinement and domain enlargement are required to ...

Abstract: In ElastoHydrodynamic Lubrication (EHL), transient processes are much more common than stationary ones. Predicting the film thickness under steady state conditions has become straight forward. Using ...

Abstract: The most time-consuming routine in the present EHL and dry contact computations is the calculation of the elastic deformation integrals. Using Multilevel Multi-Integration (MLMI) these integrals ...

Abstract: Numerical simulation of contact problems requires the calculation of the surface displacement of the contacting bodies. This is true for the lubricated contact, i.e., for elastohydrodynamic ...

Abstract: Indents perturb the pressure and stress distribution and increase the failure risk of rolling element bearings. A numerical study of the pressure perturbation is proposed. An existing dry contact ...

Abstract: Using a dry point contact model, a parametric study of the peak pressure due to a dent was performed. The parameters varied were the dent depth and diameter. The numerical analysis ws ...

Abstract: This paper investigates the influence of a transverse ridge on the film thickness in a circular EHL contact under rolling/sliding conditions. It is a numerical simulation of the optical EHL ...

Abstract: This paper investigates in detail the influence of two different surface topographies on the pressure distribution and film thickness profile of a highly loaded (maximum Hertzian pressure 2 GPa) ...

Abstract: Surface roughness and/or surface imperfections are well known to significantly affect the performance of concentrated contacts. Any deviation from the smooth surface will act as a stress raiser ...
