Nanoscale surface roughness strongly affects the adhesion force between surfaces. In this investigation, a model that more accurately describes the size of an asperity based on the measurable parameters of root-mean-square (rms) roughness and the distance between the asperities is derived. The radiu

In this paper, we investigate the adhesive contact between a rigid cylinder of radius R and a graded elastic half-space with a Young's modulus varying with depth according to a power-law, E ยผ E 0 รฐy=c 0 ร k รฐ0 < k < 1ร, while the Poisson's ratio m remains constant. The results show that, for a given
A generalization of the TOPMODEL equations for a power law vertical proยฎle of hydraulic conductivity is introduced. The exponential proยฎle of TOPMODEL is obtained as a limit case of the new general form.
