Sequential fault diagnosis strategy with imperfect tests considering life cycle costZHANG Shi-gang(张士刚), HU Zheng(胡政), WEN Xi-sen(温熙森) (Laboratory of Science and Technology on Integrated Logistics... may result in a solution with poor quality from the view of life cycle cost. Furthermore, due to the fact that uncertain information exists extensively in the real-world systems, the tests are always......

composite materials with 100, 300, and 500 cycle numbers, under the action of thermal shock load between-196 and 85 °C; the X-ray diffraction method(XRD) was used to study the change of the residual stress in the thermal shock process of the diamond/Cu composite materials; and the evolution of the fracture microstructure with different thermal shock cycle numbers was observed through scanning......
J. Cent. South Univ. (2018) 25: 1870-1878 DOI: https://doi.org/10.1007/s11771-018-3876-7 Environmental impact assessment of magnesium alloy automobile hub based on life cycle assessment YI Qiu-ping... and pollutant emission during hub production and their service life of the two types of hubs are investigated based on the life cycle assessment (LCA) theory. The results indicate that the adverse......
Trans. Nonferrous Met. Soc. China 26(2016) 1326-1335 Influence of welding on low cycle fatigue properties of Co-based superalloy FSX-414 Kh. RAHMANI, A. TORABIAN Energy... such as FSX-414 have been recently used in gas turbine first stage nozzles. During service, nozzles are exposed to low cycle fatigue, which can lead to cracking of these components. The cracks......
