个人简介

学术经历： 2003年7月和2006年6月于复旦大学获理学学士和硕士学位，2009年8月毕业于香港城市大学，获博士学位（Ph.D.）。2009年9月至2014年6月在香港城市大学（Research Fellow）和德国爱尔兰根-纽伦堡大学（Humboldt Postdoctoral Fellow, Research Associate）从事博士后的研究工作。2014年9月入职华南理工大学土木与交通学院。科研项目简介： 1．形状记忆合金（SMA）马氏体相变的解析研究（香港政府科研基金资助）建立了描述SMA马氏体相变的热力学模型，并对模型方程进行了解析求解。所得解析结果可以对马氏体相变进行全面的描述，并可揭示主要实验特征的热力学机理。 2．非线性弹性管的不稳定性研究（香港政府科研基金资助）研究了非线性弹性管的临界屈曲应力与分叉变形模式；通过耦合级数-渐进展开得到了描述后分叉变形的解析解，并与数值结果进行了比较；另外还采用奇异值理论对弹性管的缺陷敏感性进行了分析。该项目的研究成果将应用于智能材料、生物材料的研究。 3．磁致形状记忆合金（MSMA）的建模与分析（德国洪堡博士后项目）通过变分法建立了MSMA材料的本构方程组，并首次得到了单晶MSMA相变交界面移动的准则方程；基于新型迭代算法，实现了本构方程组的有限元求解；所得数值结果可以对实验结果进行精确预测并将应用于MSMA构件的设计与制造。 4．高铬钢材料蠕变与疲劳损伤的建模与分析（德国AREVA公司合作项目）通过理论建模与数值模拟，实现了对高铬钢构件热力学行为的精确预测，并对材料的蠕变和疲劳损伤进行了评估。所得研究结果获邀在MPA seminar，PVP Conference等多个国际会议作了报告，并将应用于新一代超临界发电机组中高温高压设备的设计与制造。
