The contribution deals with a class of contact optimal shape design problems the main goal of which is to drive contact stresses between elastic bodies in mutual contact. The reciprocal variational formulation is used as a tool for their numerical realization. Such a formulation makes possible to approximate directly contact stresses.

Non Contacting Stress Monitoring
2008Key input data for SIM calculations are the service stresses and the defect size. For some applications only the service stresses are required. For well designed structures this could be for stresses that arise during construction and early service life. For other situations it may be necessary to monitor crack/defect size and the local stress.

Analytical stresses in rough contacts
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2010The pressure distribution generated by rough surfaces contact induces high stresses just beneath the surface. These stresses are at the origin of several failure mechanisms such as wear, crack initiation, etc. Therefore, it is important to be able to predict these stresses.

Tyre-to-ground contact stresses
Wear, 1958Abstract Because pneumatic tyres not only carry the weight of a vehicle but propel and guide it, the study of tyre-to-ground contact stresses is one of importance. Unlike the case of metal rolling on metal the tangential forces and consequent movements between the rubber tyre and rigid ground are probably of greater importance than the normal ...

The contact stress in novikov gears
Mechanism and Machine Theory, 1989Abstract The contact stresses are calculated for a number of Novikov gear pairs, using a newly developed method for the exact determination of the principal curvatures in the teeth.

Effective Contact Stresses and Friction
Nature, 1961THE earliest statement concerning statical frictional forces between rigid bodies is usually attributed to Coulomb (about 1776). The principle of Coulombic friction is that the force (F) required to generate translation of one body relative to another is directly proportional to the external force (W) transmitted across the contact plane, so that: F ...

Contact Stresses in Rolling Bearings
2016The Hertzian pressure (normal stress) in the contact zone between the ball/roller and raceways causes a plastic deformation of the ball/roller contour. In the contact area, the oil-film thickness is nearly constant at the height h c and reduces to the height at h min at the outflow of the contact zone (cf. Chap. 4). The Hertzian pressure p H in the oil
