Theoretical and experimental investigations suggest that EHD oil films exhibit amorphous solid properties. Therefore, oil EHD traction properties may be found by the shear of corresponding molecular solids, such as amorphous paraffin. To check this p

Many technical assemblies can be modelled by a constant thickness elastic layer pressed between two elastic bodies. These models are solved up to date either by numerical methods or analytically, when the outer bodies are rigid cylinders. This paper

The paper advances a combined, analytical-numerical solution for the elastic contacts between symmetrical, fourth order polynomial surfaces. This is based on a proposal for contact area and pressure distribution which must generate forth order polyno

The cartilage has a complex mechanical behavior. One of possible cartilage models is that viscoelastic. Usually, articular pressure is found by FEM. This paper advances a simple general analytical-numerical model for the contact between a rigid punch

The mechanism of surface interaction in dry sliding is attributed either to a constant friction coefficient or to a constant friction shear stress. This paper investigates these assumptions in the case of circular rigid punches sliding against the el

Rolling contact fatigue depends essentially on both surface and subsurface populations of defects. First, this paper describes experimental results obtained in rolling contact fatigue tests in the presence of a furrow oriented transversally to the ra

Hertz theory fails when contacting surfaces are expressed by a sum of even polynomials of higher powers than two. An alternative analytical solution implies the knowledge of contact area. In the case of elliptical domains, there are some published pr

This paper investigates the dynamic contact between an axi-symmetric rigid paraboloid and a standard solid (Zener) viscoelastic half-space. The load consists of a pulse cosine applied over a step function. Following the theory developed by Ting, anal

Rolling contact fatigue is strongly influenced either by subsurface imperfections or by surface defects. The latter tend to become the major factor influencing contact fatigue. The first step to assess the effect of these defects upon contact fatigue
