Junction growth トライボロジー
Webtion growth with metals, such as gold, platinum, tin, indium, and mild steel, has been studied quantitatively by Courtney-Pratt and Eisner [5] by measuring the electrical resistance between the contacting metallic surfaces. However, junction growth has hitherto not been observed with polymers [6]. WebSep 21, 2015 · Simulations and in vivo mechanical perturbations reveal that junction growth is due to local polarized stresses driven by medial actomyosin contractions. Moreover, we find that tissue-scale pulling forces at the boundary with the invaginating posterior midgut actively participate in tissue extension by orienting junction growth. …

WebSince polymers are low thermal conductivity materials, they are affected considerably by this temperature rise. Furthermore, due to the low melting points of the polymers, thermal softening occurs because of this increase in temperature that causes considerable junction growth but results in lower shear forces needed to rupture the adhesive bonds. WebJun 20, 2008 · A model for elastic-plastic nominally flat contacting rough surfaces under combined normal and tangential loading with full stick contact condition is presented. The model incorporates an accurate finite element analysis for contact and sliding inception of a single elastic-plastic asperity in a statistical representation of surface roughness. It …
