Determination of the Plasticity Index from Flow Index

Geotechnical Testing Journal, 1999
Abstract The flow index (If), which is the slope of the water content versus log10 (number of blows) plot in the percussion cup method or the slope of the water content versus log10 (depth of penetration) plot of the cone penetration method of determining the liquid limit of soils is a measure of soil plasticity.

Contact Area and Static Friction of Rough Surfaces With High Plasticity Index

Journal of Tribology, 2010
A model for the contact area and static friction of nominally flat rough surfaces and rough spherical surfaces is presented. The model extends previously published models, which are limited to plasticity index values below 8, to higher plasticity index ...

Critical Reappraisal of Plasticity Index of Soils

Journal of Geotechcnical Engineering, 1983
A fundamental approach, based on Gouy-Chapman theory of double layer, has been provided to micromechanistically interpret the plasticity index of soils and their relationship with liquid limit. The relationships between plasticity index and liquid limit,

Plastic axial gradient-index lens

Applied Optics, 1985
An axial gradient-index (GRIN) lens, where the refractive index varies along the optical axis of a convex lens, can reduce the spherical aberration compared with the conventional homogeneous lens. The transparent plastic axial GRIN material was successfully fabricated by chemical copolymerization and diffusion techniques.

A plastics index for the food service industry: [PDF]

Academica Turistica - Tourism and Innovation Journal, 2012
Sustainability is an increasingly powerful slogan for environmental consciousness in business and commerce. For all its benefits in enabling our current living standards, the use of plastic has proven to cause significant health and environmental damage.

A general expression for plasticity index

Wear, 1988
Abstract The well-known plasticity index ψ has been widely applied in studying the contact of rough surfaces since 1966, when it was postulated by Greenwood and Williamson. Because the plasticity index ψ was derived under the implicit hypothesis that the surfaces in contact were isotropic, it was limited in application and there was some confusion ...
