Researchers at Iran University of Science and Technology Report New Data on Applied Research in Latin America

June 13, 2014



By a News Reporter-Staff News Editor at Science Letter -- New research on Applied Research in Latin America is the subject of a report. According to news originating from Tehran, Iran, by NewsRx correspondents, research stated, "Contact mechanics is related to the study of the deformation of solids that meet each other at one or more points. The physical and mathematical formulation of the problem is established upon the mechanics of materials and continuum mechanics."

Our news journalists obtained a quote from the research from the Iran University of Science and Technology, "Contact mechanics gives essential information for the safe and energy efficient design of various systems. During manipulation process, contact forces cause deformation in contact region which is significant at nano-scale and affects the nano-manipulation process. Several nano-contact mechanics models such as Hertz, DMT (Derjaguin, Muller and Toporov), JKR (Johnson, Kendall, Roberts), BCP (Burnham, Colton, Pollock)' MD (Maugis, Dugdale), COS (Carpick, Ogletree, Salmeron M), PT (Pietrement, Troyon), and Sun have been applied as the continuum mechanics approaches at nano-scale. Recent studies show interests in manipulation of biological cells which have different mechanical properties. Low young modulus and consequently large deformation makes their manipulation so sensitive. In this article contact mechanics models are used for biological cell, in air and liquid environment, then results will be compared with Tatara contact mechanics model."

According to the news editors, the research concluded: "Since biological cells are mostly modeled as visco- or hyper-elastic materials, this model will be more compatible with their condition."
