Abstract To investigate the influence of thermal treatment on rockburst in granite caverns, true-triaxial compression tests were conducted pre-heated cubic samples containing a circular through-hole using test system, and micro camera was used to monitor record process realtime. Test results show that uniaxial compressive strength elastic modulus first increase then decrease as temperature increases, which reach maximums at 200 °C sharply temperatures from 400 600 °C. The density P-wave...
To obtain the precise calculation method for peak energy density and evolution properties of rocks subjected to uniaxial compression (UC) before post-peak stage, particularly at σ ≥ 0.9σc (σ denotes stress is strength), extensive UC graded cyclical loading-unloading (GCLU) tests were performed on four rock types. In GCLU tests, unloading levels designated when < six 0.9σc. The variations in elastic (), dissipative storage efficiency (C) types under analyzed. Based variation , a calculating...
Yolk–shell structured Mo<sub>2</sub>C–C hybrid microspheres with enhanced catalytic activity for both the ORR and OER have been prepared through an <italic>in situ</italic> synthetic route.
In order to investigate the high loading rate effect on behaviour and mechanical properties of coal‐rock combined body, dynamic compressive tests were conducted by using Split‐Hopkinson Pressure Bar (SHPB) device under range from 2.7×10 5 MPa/s 4.0×10 MPa/s. The stress‐strain curves, peak stress strain, elastic modulus, energy distribution law body different rates analyzed discussed. results show that curves have a double‐peak feature range, which can be divided into initial bearing stage,...
To investigate the failure process and characteristics of D-shaped tunnels under different maximum principal stress directions θ, true-triaxial tests were conducted on cubic sandstone samples with a through hole. The test results show that can be divided into 4 periods: calm, buckling deformation, gradual exfoliation rock fragment, formation V-shaped notch. With an increase in θ from 0° to 90°, size fragments first decreases then increases, whereas fractal dimension increases decreases....
Abstract Water injection, as a widely used technique to prevent coal burst, can restrain the fractured seam and released energy storage. In this study, laboratory tests were firstly carried out on standard specimens with five different water contents (i.e., 0%, 0.6%, 1.08%, 1.5%, 2.0%, 2.3%). The failure mode, fragment size, distribution characteristics of investigated. Experimental results show that strength, elastic strain energy, dissipated brittleness index, well impact index decrease...
Abstract To investigate the effect of saturation on storage-dissipation properties and failure characteristics red sandstone, as well energy mechanism rockburst prevention by water, a series uniaxial compression loading–unloading tests were conducted under five levels. The mechanical elastic density was analyzed, method for obtaining peak proposed. evolution examined, water in preventing revealed. results indicate that an increase sandstone decreases input density, dissipated strength...
Four groups of numerical models Brazilian tests on rock-shotcrete interfaces were successfully conducted by PFC2D. The tensile strength and Young's modulus shotcrete considered. Six different undulations interface set up. influences multiple parameters the bearing characteristics studied. results showed that a better support performance can be obtained increasing rather than shotcrete. For modulus, increase sawtooth height has effects performance. failure mechanism was analysed in detail....
Herein, we first report a binder-free electrode with in situ synthesized MoP nanoflakes on the surface of carbon cloth and its application nonaqueous Li–O2 batteries (LOBs). The assembled LOBs exhibit improved discharge/charge capability (achieving actual 4.15 mAh at current 0.1 mA cycle stability, 400 cycles without capacity fading), which should be attributed to superior electrocatalytic activity toward formation/decomposition Li2O2.
