J. Cent. South Univ. (2016) 23: 926-933 DOI: 10.1007/s11771-016-3140-y Viscoelastic micromechanical model for dynamic modulus prediction of asphalt concrete with interface effects DONG Man-sheng(董满生... interface between asphalt mastic and aggregates on the overall viscoelastic characteristics of AC. The linear spring layer model is introduced to simulate the interface imperfection. Based......
) with interface stresses was derived by means of the MOTT and NABARRO’s model. The influence of interface stresses on the critical shear stress was examined. The result indicates that, if the volume fraction of the core-shell nanowires keeps a constant, an optimal critical shear stress may be obtained when the radius of the nanowire with interface stresses reaches a critical value, which differs from......
was gone back to the electronic scale of atomic bonding by using the empirical electronic theory (EET) in solid and molecule and the improved interface TFD theory established based on bond theory and band theory. The investigation of interface bonding feature of the atomic bonding of sequence phase and the atomic bonding at the interface between the matrix and the precipitate in Al-Mg-Si alloy......

will be opened. The third case opens all the cooling channels at the same time. The results indicate that in the second case, the solid-liquid interface keeps near-planar. The growth velocity of the solid-liquid interface is 0.3-0.4 mm/s, which is greater than 0.1-0.3 mm/s of the first case, performing better than the others. Thus the forming quality and efficiency part interior can be improved by mold......
marks of steel strip of a temper mill, it was discovered that the chatter marks is closely related to self excited vibration of the system. This kind of vibration originates from rolling interface, where partial fluid lubrication and viscous slip coexist.
