J. Cent. South Univ. (2016) 23: 2838-2844 DOI: 10.1007/s11771-016-3347-y Fragmentation mechanism of low-grade hematite ore in a high pressure grinding roll YUAN Zhi-tao(袁致涛)1, LI Li-xia(李丽匣)1, HAN...-grade hematite ore in a high pressure grinding roll (HPGR) was studied based on the characteristics of comminuted products at different specific pressure levels. The major properties included......
J. Cent. South Univ. Technol. (2008) 15(s1): 316-321 DOI: 10.1007/s11771-008-371-6 Prediction of shear bands in sand based on granular flow model and two-phase equilibrium ZHANG Yi-tong(张义同)1... equilibrium and the slow plastic flow model are applied to predict the formation and patterns of shear bands in sand specimens, discontinuity of deformation gradient and stress across interfaces......
Special nanostructures in Al-Mg alloys subjected to high pressure torsion LIU Man-ping(刘满平)1, 2, Hans J. ROVEN2, LIU Xin-tao(刘新涛)1, Maxim MURASHKIN3, Ruslan Z. VALIEV3, Tamas UNG?R4, Levente... to high pressure torsion. These observations are surprising because deformation twinnings have never been observed in their coarse-grained counterparts under normal conditions. Experimental evidences......

J. Cent. South Univ. (2017) 24: 2154-2163 DOI: https://doi.org/10.1007/s11771-017-3624-4 Limit equilibrium analysis for rock slope stability using basic Hoek–Brown strength criterion DENG Dong-ping...: Hoek–Brown (HB) strength criterion can reflect rock’s inherent failure nature, so it is more suitable for analyzing the stability of rock slopes. However, the traditional limit equilibrium methods......
