Trans. Nonferrous Met. Soc. China 24(2014) 1506-1511 Flow equation and similarity criterion during centrifugal casting in micro-channel Ming-xing REN1, Guo-tian WANG2, Bang-sheng LI1, 2, Zhen-long...;derived similarity criterion. Based on the traditional flow equations, the flow equation and the Bernoulli’s equation for liquid metal flows in micro-scale space were derived, which provides......
Power, Southwest Jiaotong University, Chengdu 610031, China; 2. CRRC Qingdao Sifang Co. Ltd., Qingdao 266111, China) Abstract: By analyzing the five basic characteristics of the failure criterion...-M strain failure criterion and GISSMO failure criterion. The results show that the GISSMO failure criterion has great advantages in describing the failure behavior of isotropic ductile materials......

Characterization of deformation stability of in-situ TiB2/6351 composites during hot compression based on Murty criterion GUO Sheng-li(郭胜利)1, LI De-fu(李德富)1, CHEN Dong(陈 东)2, WANG Hao... the criterion developed by KUMAR and PRASAD[7]. The criterion was developed on the basis of the continuity principle applied to large plastic flow by ZIEGLER[8], according to which instability occurs when......
Determination of strain criterion of Portevin–Le Chatelier effect for aluminum alloy sheets WAN Min(万 敏)1, HAN Jin-quan(韩金全)1, JIN Hai-xia(金海霞)1, WU Hui(伍 惠)2, DONG Jin-liang(董锦亮)2, LI Bing(李 兵)2..., but it consequentially reduces the shape fixability of skin parts. Hence, an accurate criterion is required in mirror skin forming to avoid the slip lines ocurring. It is one of key issues in aluminum mirror......
