J. Cent. South Univ. (2021) 28: 1857-1874 DOI: https://doi.org/10.1007/s11771-021-4735-5 Energy evolution mechanism and failure criteria of jointed surrounding rock under uniaxial compression LI... the energy evolution mechanism and failure criteria of cross-jointed samples containing an opening during deformation and failure based on the uniaxial compression test and rock energy principle......
J. Cent. South Univ. (2016) 23: 3312-3321 DOI: 10.1007/s11771-016-3397-1 Model test to investigate failure mechanism and loading characteristics of shallow-bias tunnels with small clear distance LEI..., a tunnel excavation simulation testing system under typical unsymmetrical loading conditions was established. Using this system, the failure mechanism of surrounding rock of shallow-bias tunnels......
Progressive failure processes of reinforced slopes based ongeneral particle dynamic methodZHAO Yi(赵毅)1, 2, ZHOU Xiao-ping(周小平)1, 2, 3, QIAN Qi-hu(钱七虎)4(1. State Key Laboratory of Coal Mine Disaster... deformation and failure of geomaterials. The Mohr-Coulomb strength criterion was implemented into the code to describe the elasto-brittle behaviours of geomaterials while the solid-structure......
Pressure-impulse diagram with multiple failure modes of one-way reinforced concrete slab under blast loading using SDOF methodWANG Wei(汪维)1,2, ZHANG Duo(张舵)1, LU Fang-yun(卢芳云) 1, TANG Fu-jing (汤福静... subjected to explosive loading. Blast test results show that the SDOF systems are accurate in predicting the failure mode of the slab under blast loads by incorporating the effects of the strain rate......
