libisemisomadusi

Libisemisomadusi is a term used in materials science and geotechnical engineering to describe the tendency of a surface or material to undergo sliding under a tangential load. It encompasses how easily relative motion starts and continues at an interface, as well as how readily motion is sustained once initiated.

The concept is related to, but distinct from, the coefficient of static friction. While μs quantifies resistance to initial slip, libisemisomadusi emphasizes the ease of slip under given conditions, influenced by surface roughness, moisture, temperature, lubrication, and normal load. It can be characterized by the critical shear stress τc required to initiate slip, or by slip ratio under a controlled shear test.

Measurement and interpretation: In geotechnical contexts, slip tendency is evaluated through stability analyses and factors of safety against sliding along potential failure planes. In tribology, laboratory tests such as pin-on-disk or inclined-plane experiments measure τc and μ, from which libisemisomadusi is inferred. The property depends on contact conditions, including material pair, contaminants, and ambient conditions.

Applications and relevance: Understanding libisemisomadusi helps in designing stable slopes, selecting lubricants, and controlling handling of powders and films. It is particularly important in systems where slip can lead to failure or unwanted motion, such as rock slopes, ice sheets, and industrial conveyors.
