J. Cent. South Univ. Technol. (2011) 18: 1-5 DOI: 10.1007/s11771-011-0650-5 A unified criterion for yielding behavior of metallic glasses SONG Min(宋旼), HE Yue-hui(贺跃辉) State Key Laboratory... was studied. Three yield criteria, including von Mises yield criterion, Mohr-Coulomb yield criterion and the unified yield criterion were used to describe the yield phenomena of the metallic glasses. Two......
, and test data showed that the strength envelopes of the soils followed power-law failure criterion. In this work, deep buried highway tunnel with large section was taken as objective, and the basic expressions of collapse shape and region were deduced for the highway tunnels in soils, based on kinematical approach and power-law failure criterion. In order to see the effectiveness of the proposed......
Creep failure mode and criterion of Xiangjiaba sandstoneWANG Wei(王伟)1,2, LI Liang-quan(李良权)3, XU Wei-ya(徐卫亚) 1,2, MENG Qing-xiang(孟庆祥) 1,2, LÜ Jun(吕军) 1,2(1. Key Laboratory for Geomechanics... in short-term tests and creep tests, fractography of sandstone after creep failure, short-term and creep failure criterion are analyzed. In the short-term tests and creep tests, the sandstone samples......

A DUCTILE FRACTURE CRITERION BASED ON THREE-DIMENSIONAL VOID MODEL X.H.Dong1,J.K.Huang1 (1.National Die & Mould CAD Engineering Research Center, Shanghai Jiaotong University, Shanghai 200030,China) Abstract:A fracture criterion derived from a microscopic point of view is proposed and has proved to be effective in the analysis of uniaxial tension. On the one hand, a method of predicting......

South University Press and Springer-Verlag Berlin Heidelberg 2012 Abstract: Based on Mohr-Coulomb (M-C) criterion, the parameters of Druker-Prager (D-P) criterion for geomaterial were determined under......
J. Cent. South Univ. (2020) 27: 3807-3820 DOI: https://doi.org/10.1007/s11771-020-4563-z Unified strength model based on the Hoek-Brown failure criterion for fibre-reinforced polymer-confined pre... by regression analysis of experimental data; however, in this article, a new unified strength model is proposed using the Hoek-Brown failure criterion. To study the strength of FRP-confined damaged......
A Novel Criterion of Mixing Time in Gas-Stirred Ladle SystemsJun Zhang22. School of Metallurgy and Resource, Anhui University of Technology摘 要:A novel criterion of mixing time in gas-stirred ladle systems was proposed in this paper. The essential difference between the previous criterion and the present one is that the former is based......
