Analysis of the Influence of Contact Stress on the Fatigue of AD180 High-Carbon Semi-Steel Roll
MetalsIn this study, to investigate the problem of contact fatigue and the damage mechanism of an AD180 high-carbon semi-steel roll, rolling contact fatigue tests were conducted using specimens cut from the periphery of a roll ring.

A thin rivulet or ridge subject to a uniform transverse\ud shear stress at its free surface due to an external airflow [PDF]
, 2012 We use the lubrication approximation to analyse three closely related problems involving a thin rivulet or ridge (i.e. a two-dimensional droplet) of fluid subject to a prescribed uniform transverse shear stress at its free surface due to an external ...

Stress concentration in periodically rough hertzian contact: Hertz to soft-flat-punch transition
, 2016 We report on the elastic contact between a spherical lens and a patterned substrate, composed of an hexagonal lattice of cylindrical pillars. The stress field and the size of the contact area are obtained by means of numerical methods (discrete Green's ...
