    Progressive Collapse Resistance Mechanism of RC Frame Structure Considering Reinforcement Corrosion by Chao Bao, Dahai Lv, Huxiang Wang, Yuhang Zhang, Xiaotong Ma, Kar Sing Lim, Juping Zhang

    Published 2023-01-01
    “…Corrosion causes reduction in cross-sectional area of reinforcement, deterioration of mechanical properties, and degradation of bonding properties between reinforced concrete, which are the most important factors leading to the degradation of structural service performance. In order to investigate the progressive collapse mechanism of a corroded reinforced concrete frame structure, the failure modes, characteristics of the vertical displacement, and load capacity are studied using the finite element method. …”

    Damage analysis and optimal design of micro-structure milling cutter based on peridynamics. by Zhongwei Ren, Jing Deng, Hongwan Jiang, Sen Yuan, Xi Yue, Chuchun Tian

    Published 2024-01-01
    “…When the milling time is 3.5×10-6 s, the tool's major cutting edge combined displacement increases most rapidly, the major flank optimization effect is the most obvious, and the resultant displacement is reduced by about 37.06%. By optimizing the structural parameters of micro-grooves on the rake face, this study enhances the comprehensive performance of the tool and unveils the formation, distribution, and variation patterns of near-field cracks on the tool's cutting edge. …”

    Climate regulates alpine lake ice cover phenology and aquatic ecosystem structure by Daniel L. Preston, Nel Caine, Diane M. McKnight, Mark W. Williams, Katherina Hell, Matthew P. Miller, Sarah J. Hart, Pieter T. J. Johnson

    Published 2016-05-01
    “…Abstract High‐elevation aquatic ecosystems are highly vulnerable to climate change, yet relatively few records are available to characterize shifts in ecosystem structure or their underlying mechanisms. Using a long‐term data set on seven alpine lakes (3126 to 3620 m) in Colorado, USA, we show that ice‐off dates have shifted 7 days earlier over the past 33 years and that spring weather conditions—especially snowfall—drive yearly variation in ice‐off timing. …”
