In this study, the fractal characteristics and energy dissipation behavior of gas-bearing coal are explored under both dynamic static loads. Multifactor coupling mechanical tests conducted using visualized loading experiment systems. The effects impact velocity, axial compressive stress ratio, initial gas pressure on fragmentation analyzed. An internal correlation between debris density is clarified considering fact that distribution has prominent in log–logarithmic coordinates. It...
Due to the low permeability and apparent mechanical anisotropy of shale reservoirs, oil production highly depends on performance hydraulic fracturing tight reservoir. Pre-injection CO2 before treatment has been proven beneficial enhance production. A comprehensive understanding effect changes in properties reservoirs after preinjected behavior is essential improve stimulated reservoir volume (SRV) reservoirs. In this study, evaluating parameters were proposed specify variation rock at...
This article aims at investigating the meso-scale mechanisms that result in failure by strain localization soil and rock mixtures (SRM). While macroscopic of SRM has been widely studied, physical governing deformation have not well understood. A uniaxial compressive test on sample was performed under tomographic monitoring using a 450 kV industrial X-ray computed tomography (CT). series 2D CT images were obtained carrying out scanning key points throughout from different positions sample....
Abstract The in‐situ V 8 C 7 ‐V 3 B 4 /Fe45 composites were fabricated by vacuum sintering using ferrovanadium, carbon black and Fe45 alloy powders as raw materials. microstructure, phase structure hardness of sintered Fe45+x wt.% (FeV+C) composite specimens (x = 0, x 5, 10, 15, 20) investigated. results show that the type shape borides carbides depend on content mixed powders. When consists α‐(Fe, Cr, V) solid solution, strip M block 2 borides. particles initiate inside precipitation,...
