Network-Configurations of Dynamic Friction Patterns
, 2012 The complex configurations of dynamic friction patterns-regarding real time contact areas- are transformed into appropriate networks. With this transformation of a system to network space, many properties can be inferred about the structure and dynamics ...

Speed and Atmosphere Influences on Nanotribological Properties of NbSe2 [PDF]
, 2009 Nanotribological properties of NbSe2 are studied using an atomic friction force microscope. The friction force is measured as a function of normal load and scan speeds ranging from 10 nm s−1 to 40 μm s−1 under two atmospheres (air and argon).

Shear-Compression Failure Condition of Key Strata Under Elastic Support During Periodic Breakage
Applied SciencesThe shear-compression failure of key strata leads to stair-step collapse and severe mine pressure, posing significant safety risks in coal mines. Existing theories fail to account for the boundary conditions and breaking sizes of key strata, making ...

Characteristics of direct shear test for plain concrete joint with rubber cushion
矿业科学学报, 2018 The contact friction between the segments and the joints of shield segments plays a crucial role in the stability of the shield segment.In order to analyze the contact friction among tunnel segments,direct shear tests were carried out on concrete ...

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam
Advanced Engineering Materials, EarlyView.Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...

Experimental analysis and modeling of orthogonal cutting using material and friction models [PDF]
, 2007 In this study, a process model for orthogonal cutting processes is proposed. The model involves the primary and secondary deformation zones. The primary shear zone is modeled by a Johnson-Cook constitutive relationship and a shear plane having constant ...

, 2019 The shear-jamming of dense suspensions can be strongly affected by molecular-scale interactions between particles, e.g. by chemically controlling their propensity for hydrogen bonding. However, hydrogen bonding not only enhances interparticle friction, a

Frictionless bead packs have macroscopic friction, but no dilatancy [PDF]
, 2008 The statement of the title is shown by numerical simulation of homogeneously sheared packings of frictionless, nearly rigid beads in the quasistatic limit. Results coincide for steady flows at constant shear rate γ in the limit of small γ

Shear thinning in non-Brownian suspensions explained by variable friction between particles
Journal of Fluid Mechanics, 2018 We propose to explain shear-thinning behaviour observed in most concentrated non-Brownian suspensions by variable friction between particles. Considering the low magnitude of the forces experienced by the particles of suspensions under shear flow, it is ...
