Contact Area Effects on Discomfort
Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1994Most “ergonomic” products attempt to adopt a uniform force distribution strategy to improve comfort. The rationale being that force distribution over a large area reduces pressure and thereby enhances user comfort. However, sensory literature alludes to the concept of spatial summation, i.e.

Inhomogeneous ohmic contacts: Barrier height and contact area determination
Applied Physics Letters, 2012The current-voltage characteristics at a uniform ohmic contact are, by definition, dominated by its series resistance and ordinarily offer little information, beyond an upper-bound, on the Schottky barrier height (SBH) of the metal-semiconductor junction.

Large Area Submicrometer Contact Printing Using a Contact Aligner
Langmuir, 2000Submicrometer patterns were produced in a thin layer of gold over a 3 in. diameter substrate with an accuracy of ≥40 nm and a runout (feature to feature misalignment between the template and the st...

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 ...

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.

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.

Tribological and Contact Area Effects
2014In order for the electroplastic effect to take place, the applied electricity must be able to flow from the dies and through the workpiece. Because of this, the interfaces between the dies/workpiece are critical.

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 ...

Area of Contact Between Solids
2001Abstract It is a very difficult matter to prepare surfaces which are really flat. Even on carefully polished surfaces, hills and valleys are present which a.re large compared with the size of a, molecule. If two solids are placed in contact, the upper surface will be supported on the summits of the irregularities, and large areas of the ...
