Submicron Volume Roughness & Asperity Contact Friction Model for Principle Slip Surface in Flash Heating Process

doi: 10.1007/s12583-015-0514-2

Abstract: 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.
