Frictional dermatitis from touchscreen contact
Pediatric Dermatology, 2022AbstractFrictional dermatitis occurs after prolonged or repetitive physical contact of the skin with a surface and usually presents as a pediatric or occupational dermatosis. A 10‐year‐old girl presented with painful erythematous, edematous plaques, and macules on the fingertips within 24 h of playing a game requiring her fingers to repeatedly slide ...

AbstractFrictional trauma to the palms and fingertips can provoke a dermatitis. Cases of frictional dermatitis have been recognized in workers handling large quantities of pressure‐sensitive carbonless paper. Elimination of the trauma led to healing within 2–3 weeks.

In this chapter, we show how the HHO method can be used to discretize a linear elasticity problem with nonlinear boundary conditions resulting from contact and friction. The main idea is to use a boundary penalty technique to enforce these conditions.

Our understanding of friction and mechanism of energy dissipation has undoubtedly experienced a tremendous profit after the introduction of scanning probe microscopy. Nowadays the tribological response of a sliding asperity can be easily traced down to the atomic scale.

FRICTIONAL VISCOELASTIC CONTACT
The Quarterly Journal of Mechanics and Applied Mathematics, 1986It is shown that, in a previous treatment of this topic [the author, ibid. 32, 25-52 (1979; Zbl 0409.73093)], the expression used for the coefficient of hysteretic friction was incomplete. Corrected expressions for this quantity are derived from a treatment of the problem which is more general, and in some respects more compact and elegant, than the ...

Brush Friction and Contact Losses
Transactions of the American Institute of Electrical Engineers, 1913It is apparent from the foregoing that the niceties of adjustment found necessary in obtaining coefficient of friction show the hopelessness of determining the true friction loss by the method outlined in the existing Standardization Rules. It is evident that in measuring brush friction by reading the input to, the machine with brushes up and brushes ...

Frictional Heating of Elliptic Contacts
1994Wherever friction occurs mechanical energy is transformed into heat. The maximum surface temperature associated with this heat generation can have an important influence on the tribological behaviour of the mating components. For band contacts and circular contacts this temperature has already been studied extensively.

Contact Mechanics: Friction and Wear
1998Contact mechanics describes the stresses and the deformations in the neighbourhood of the contact between two pressed bodies. The following examples are given: concentrated and distributed normal and tangential loads, point load, pressure on a circular surface, hertzian contact for normal and tangential loadings.

Contact, Support, and Friction
Sociological Perspectives, 1986The networks literature has been bedeviled by an assumption that networks convey supportiveness to the exclusion of conflict. In this article, we discuss a method for distinguishing conflict, support, and simple contact network linkages in surveys.
