(2016) 23: 344-352 DOI: 10.1007/s11771-016-3079-z Transient reliability optimization for turbine disk radial deformation Fei Cheng-wei(费成巍)1, 2, Bai Guang-chen(白广忱)2, Tang Wen... 2016 Abstract: The radial deformation design of turbine disk seriously influences the control of gas turbine high pressure turbine (HPT) blade-tip radial running clearance (BTRRC). To improve the design......
Introduction Radial forging is an open-die forging process which usually uses two pairs instead of one pair of opposing dies, and its incremental deformation results from a large number of short-stroke... relatively satisfactory homogeneous performance, these process parameters including the axial feed, the radial reduction, the rotation rate, the geometry of hammers, and the initial temperature......
J. Cent. South Univ. Technol. (2009) 16: 0887-0891 DOI: 10.1007/s11771-009-0147-7 Deformation and defects in hydroforming of 5A06 aluminum alloy dome with controllable radial pressure XU Yong... deformation behavior demands an appropriate chamber pressure pc with deformation. On one side, the chamber pressure cannot be too high, in order to avoid the serious thinning due to a large radial......
particles will drop off the trend of particle aggregation, and in turn, the decrease of this trend will make original inhomogeneous structures in the systems more homogeneous. Fig.1 Comparison of radial...

Factors affecting accuracy of radial point interpolation meshfree method for 3-D solid mechanicsPENG Chong(彭翀), YUAN Hui-na(袁会娜), ZHANG Bing-yin(张丙印), ZHANG Yan(张琰) (State Key Laboratory of Hydroscience and Engineering (Department of Hydraulic Engineering, Tsinghua University), Beijing 100084, China)Abstract:Recently, the radial point interpolation meshfree method has gained popularity owing......
three types to one type of tension, and the homogeneity of the deformation as well as metal flow are greatly improved. The non-homogeneous metal flow at the final stage of extrusion is improved... pocket in the form of parallelogram, which indicates that the deformation and flow of the metal are homogeneous. Therefore, it is easy for the metal to flow out the die pockets without the formation......
