J. Cent. South Univ. (2018) 25: 2069-2075 DOI: https://doi.org/10.1007/s11771-018-3896-3 Fatigue life prediction of workpiece with 3D rough surface topography based on surface reconstruction... of surface quality is commonly accounted for by using empirical correction factors, which is imprecise when safety is of great concern. For surface quality, the surface topography is an important parameter......

J. Cent. South Univ. (2016) 23: 2419-2428 DOI: 10.1007/s11771-016-3301-z Aerodynamic performance analysis of trains on slope topography under crosswinds LIU Tang-hong(刘堂红)1, 2, SU Xin-chao(苏新超)1, 2... the computational fluid dynamics method combined with full-scale train tests to analyze the train aerodynamic performance on special slope topography. Results show that with the increment in the slope......
surfaces. In most cases, the design and simulation of a functional surface require both complete definition of the overall shape of the surface and the full specification of its topography at microscopic scale. In this regards, the design of surface topography needs mathematic modelling and identification of optimal values for design parameters by considering their relationship with functional......
. The principle of the fracture-surface topography analysis (FRASTA) was used. In FRASTA, the fracture surfaces were scanned by laser microscope and the elevation data was recorded for analysis... matches each other well. Key words:FRASTA (fracture-surface topography analysis); J-integral; fracture surface; [全文内容正在添加中] ......
