Jianzhu Gangjiegou Jinzhan基于常用结构奥氏体不锈钢S30408、S31608以及双相不锈钢S22053的循环加载试验结果，提出了基于经典混合硬化模型的改进遗传算法和自适应子步积分方法联合使用的模型参数快速标定方法。试验表明，3种牌号的结构不锈钢在大应变幅度下的循环硬化/软化行为普遍表现出明显的应变幅值依赖性和断裂前的硬化不饱和性，这与常用的碳素钢有显著差异。结果表明，该方法相较于传统标定方法显著减少了人工工作量和时间成本，且具有良好的精度和广谱性，更适用于不锈钢等不存在稳定滞回环的循环硬化不饱和及Non-Masing材料 ...

Investigation of particle impact on 304SS under the liquid-solid two phase flow [PDF]
, 2017 随着社会工业、经济的发展，对能源的需求量日益增加，与此同时也造成了日益严重的环境污染问题。因此，能源结构的调整显得越发重要与急迫。核能具有环保、清洁、能量密度高的特点，弥补了新能源能量密度低的不足，避免了传统化石能源对环境的危害。自1954年世界上第一座核电站并网发电以来，核能得到了较大的发展，然而其安全性影响了核电持续、稳定、长远的发展。 在核电站正常运行时，颗粒状腐蚀物如铁屑、铜屑、细砂等，于二回路、三回路中与流动的流体形成液固两相流。液固两相流会对管道壁面进行磨损-腐蚀行为，导致材料的损耗 ...
