Bem frictional contact analysis: Load incremental technique

Computers & Structures, 1993
A boundary element formulation for solving structural problems associated with frictional contact is presented; it uses an efficient, iterative and fully load-incremental technique. Problems with any number of two- dimensional bodies in contact can be analysed using this technique; the bodies may be conforming or nonconforming, of similar or dissimilar

The virtual contact loading method for elastic contact problems

Communications in Numerical Methods in Engineering, 1993
AbstractThe virtual contact loading method (VCLM), a highly efficient numerical method to solve elastic contact problems, is proposed in this paper. Having applied virtual loads on the possible contact region (PCR) of a structure system, we carried out the usual finite‐element calculations only once and made a local iteration analysis in PCR then the ...

Thermal contact conductances of metallic contacts at low loads

Applied Energy, 1990
Experimental investigations on thermal contact conductances of metallic contacts have been reported here. The studies are restricted to relatively low contact pressure: hardness ratios $(< 0.7 \times 10^{-3})$ where very little data exist. These results have applications in situations like some types of electrical contacts, cooling of electronic ...

BRIDGE VIBRATION UNDER VEHICULAR LOADS: TIRE PATCH CONTACT VERSUS POINT CONTACT

International Journal of Structural Stability and Dynamics, 2010
When establishing the equations of motion of the bridge-vehicle coupling system, most researchers simplify the contact between the vehicle tire and road surface as a point contact. In reality, a vehicle tire deforms and makes contact with the road surface over a footprint area called patch contact.

Lubricant behaviour in loaded rubber contacts

Wear, 1975
Abstract In some work on the lubrication of soft contacts using optical interferometry a number of effects have been brought to light which are complementary to work of Gaman, Higginson and Harman [1]. In the present work the normal approach of a rubber specimen to a flat glass plate is taken to the point where the lubricant completely disappears.

Dependency of Contact Resistance on Load

Electrical Contacts - 2007 Proceedings of the 53rd IEEE Holm Conference on Electrical Contacts, 2007
Recently characteristics required of automobiles have been diversified, and from the electric/electronic points of view, the changes of automobiles are a wide range of electronization flow of control and changes of power source of automobiles represented by electric automobiles and the transmission system.

Fatigue of alumina under contact loading

Engineering Fracture Mechanics, 2003
Abstract Bars cyclically loaded by opposite concentrated forces via rollers are appropriate test specimens for the determination of fatigue under contact loading. As practical applications of the proposed test, the contact strengths and numbers of cycles to failure under contact loading were determined for three Al 2 O 3 .

Contact resistance on freshly cleaned contacts at very small contact loads

1958
The measurements were made in F. L.2 with the aid of a modified moving-coil instrument. The pointer, provided with a very good bearing, carried one contact member, the other being stationary, see Fig. (10.01). The contact load or sometimes tension was generated by means of the current through the coil.

Characterizing Frictional Contact Loading via Isochromatics

Experimental Mechanics, 2014
Isochromatic patterns in the vicinity of frictional contacts furnish vital clues for characterizing friction. Though friction effects are evident in a diametrally loaded circular disk, three-point loading provides better results towards highlighting friction.
