This work aims to investigate the mechanical behaviour of medium-grained sandstones under cyclic loading with different loading/unloading rates. type is called differential (DCL) and considered for testing rock behaviour. In experiments, constant amplitude multi-level loadings were performed. Three modes designed consider relationships between unloading Axial strain evolution energy dissipation analysed rates maximum load level. The correlations P-wave velocities strengths rocks deduced from...
In numerical simulation of the mechanical responses and acoustic emission (AE) characteristics rocks under cyclic loading, impacts compositional heterogeneities mineral grains have barely been considered. This will lead to a poor reproduction rock's behaviors in terms stress-strain relationship micro-seismic simulation. work aims analyze reveal impact parameter heterogeneity on fatigue properties based PFC3D. Two distribution patterns (uniform Weibull distributions), are implemented assign...
Ferroptosis was reported to be involved in cerebral ischemia-reperfusion injury (CIRI), on which the effects of berberine (BBR) remain unclear. Moreover, based critical role gut microbiota pleiotropic actions BBR, we hypothesized that BBR can suppress CIRI-induced ferroptosis by modulating microbiota. In this study, results showed obviously attenuated behavioral deficits CIRI mice, accompanied with improved survival rate and neuron damages, as phenocopied dirty cage experiment. The typical...
Abstract This work presents particle-based numerical simulations on coal pillars in a mine based underground water reservoir (CMUWR). We aim to replicate the stress–strain characteristics and present acoustic emission behavior of under complex dynamic stress paths. The study reveals failure exposed monotonic/cyclic shear load constant/cyclic normal loads. Based evolution stress-time-dependent bond diameter implemented particle model, different damage paths are established for dry...
Abstract The stability of coal walls (pillars) can be seriously undermined by diverse in-situ dynamic disturbances. Based on a 3D particle model, this work strives to numerically replicate the major mechanical responses and acoustic emission (AE) behaviors samples under multi-stage compressive cyclic loading with different unloading rates, which is termed differential (DCL). A Weibull-distribution-based model heterogeneous bond strengths constructed both considering stress–strain relations...
