Submicron Volume Roughness & Asperity Contact Friction Model for Principle Slip Surface in Flash Heating Process
نویسندگان
چکیده
Based on focused ion beam and shear friction apparatus data, the multi-resolutions (0.2 nm–5 μm) volume roughness & asperity contact (VR & AC) three-dimensional structure on principle slip surface interface-surface (PSS-IS) is measured on high performance computational platform; and physical plastic-creep friction model is established by using hybrid hyper-singular integral equation & lattice Boltzmann & lattice Green function (BE-LB-LG). The correlation of rheological property and VR & AC evolution under transient (10 s) macro-normal stress (18–300 MPa) and slip rate (0.25–7.5 m/s) are obtained; and the PSS-IS friction in co-seismic flash heating is quantitative analyzed for the first time.

Slip weakening in rocks and analog materials at co-seismic slip rates
Determination of co-seismic slip resistance in earth faults is critical for understanding the magnitude of shear-stress reduction and hence the near-fault acceleration that can occur during earthquakes. Also, knowledge of shear resistance dependency on slip velocity, slip distance, normal stress, and surface roughness is fundamental information for understanding earthquake physics and the energ...
متن کاملEffect of surface roughness on steel-steel dry friction coefficient
The influence of surface roughness magnitude and direction on dry static friction coefficient between two similar steel samples has been studied through an experiment. A testing apparatus has been designed and fabricated to measure the friction coefficient for a few forms of surface asperity. According to the results of the experiments, dry friction coefficient is affected by both magnitude and...
متن کاملNano-Scale Effect in Adhesive Friction of Sliding Rough Surfaces
Study of contact and friction at multiple length scales is necessary for the effective design and analysis of surfaces in sliding microand nano-electromechanical systems (MEMS/NEMS). As loading forces decrease in such applications, the size of the asperity contacts tends to decrease into the nano scale regime. Also with the increase in surface area to volume ratio in such systems, the surface f...
متن کاملMicromechanics of Rough Interfaces
The mechanical behavior of rough interfaces is modeled from a micromechanical viewpoint. A kinematically driven mechanistic approach is adopted which explicitly considers the interaction of asperities on the fracture surface. The mating asperities are assumed to behave in accordance with contact mechanics postulates of non-conforming bodies. The roughness of the fracture surface is represented ...
متن کاملA model for flash weakening by asperity melting during high-speed earthquake slip
[1] Recent results from laboratory experiments on a broad range of mineral systems exhibit dramatic drops in the effective friction coefficient m once the slip rate exceeds a critical level Vw, which is typically O(0.1) m/s. This ‘‘flash weakening’’ has been attributed to the effects of localized heating at highly stressed microscopic asperities. We extend previous phenomenological treatments t...
