Study on the evolution law of acoustic emission time series characteristics of coal-rock assemblage under true triaxial conditions
Published 2025-05-01“…IntroductionThis study aims to investigate the fractal characteristics of acoustic emission (AE) signals during coal-rock rupture and their predictive significance for impact dynamic hazards.MethodsTrue triaxial loading/unloading tests were conducted on five coal-rock composites with varying coal-thickness ratios using the TRW-3000 system, with AE signals analyzed to correlate stress evolution and temporal-spatial fractal features.ResultsKey findings reveal that: 1) AE parameters exhibit stress-dependent behavior, growing slowly initially, stabilizing during stress-holding, and surging exponentially before peak stress, with ∼90% of cumulative energy released pre-destabilization; 2) Ring counts follow an Λ-type trend against absolute energy, while coal-thickness proportion induces a mirror-image N-type pattern in AE parameters; 3) High-energy/high-ringcount AE events cluster spatiotemporally before failure, with clear time sequence precursors—short-duration ground sounds and consecutive rises in energy/frequency serve as critical early-warning indicators, whereas isolated signals lack hazard relevance.DiscussionThese fractal patterns and precursor thresholds enhance real-time monitoring and risk assessment frameworks, offering actionable strategies for mitigating coal-rock dynamic disasters in underground mining.…”

Design and application of a three-dimensional skeletonized structure for distal radius fracture splinting based on 3D printing technology
Published 2025-05-01“…The test results demonstrate that, under pressure of 150 N, the radial offset of the 3D printed splint is reduced by 1.7 mm compared to that of the traditional small splint, with a corresponding decrease in stress by 0.01 MPa as well. In terms of weight, a set of 3D printed splints weighs 89 g while a set of conventional splints weighs 102 g, resulting in a significant reduction of 13 g for the 3D printed splints compared to their traditional counterparts. …”
