On the Contact Area of Nominally Flat Hertzian Contacts
Tribology Letters, 2016In a recent paper, Pastewka and Robbins (Appl Phys Lett 108:221–601, 2016) state an analytical expression for the real contact area of a Hertzian tip with small-scale roughness. We confirm that their formula predicts real contact areas quite well—with less than 10 % error.

Determination of the actual contact area during sliding contact
Wear, 1981Abstract A new method for determining the actual contact area of conducting samples by measuring the total electrical resistance of the contacting pair is described. The results of experimental determinations of the actual contact area are given and discussed.

Clinical Orthopaedics and Related Research, 1995
Sixteen fresh ankle specimens were tested under physiologic loads to evaluate the effect on the tibiotalar contact area of increasing-size posterior malleolar fracture fragments and disruption of the deltoid ligament. The tibiotalar joint was maintained in a neutral position, and contact areas were recorded on pressure sensitive film.

Adhesive Contact of Bodies Having an Elliptical Contact Area
World Tribology Congress III, Volume 1, 2005The so-called JKR theory of adhesion between elastic spheres in contact (Johnson, Kendall & Roberts 1971, Sperling 1964) has been widely used in micro-tribology. In this paper the theory is extended to solids of general shape and curvature. It is assumed that the area of contact is elliptical which turns out to be approximately true, though the ...

A Dynamical Model for the Plane Contact with Rigid Contact Areas
2007In this article a generalized elasto-plastic model for the plane frictional contact of rigid bodies is presented. The basic assumptions for this model are the rigidness of the plane contact area and locally acting friction.

Contact area of rough surfaces
Wear, 1960Abstract An analysis is given of the contacting process of surfaces that are rough and wavy. The authors use three contact areas: apparent, contour and real. A unit protrusion is modelled as a cone with a spherical top deformed elastically and plastically.

Joint Contact Area and Pressure
1991During the later half of the past decade a considerable amount of information on the biomechanics of the human wrist has been uncovered by measuring the contact areas and pressures in cadaver wrists in a variety of normal, simulated post-traumatic, and surgically treated conditions.

Intermetallic diffusion and contact areas
Wear, 1972Abstract The present work attempts to make use of the phenomena of intermetallic diffusion, together with an analysis of the extent to which it can occur under known conditions, as a possible means of providing information on contact areas. The results obtained from electron probe micro-analysis of interdiffusion occurring between two metals which ...
