助理教授 力学与航空航天工程系   课题组网站

刘巨助理教授于2008年毕业于西安交通大学,获得理学学士学位。之后赴美国德克萨斯大学奥斯汀分校学习计算力学,并于2014年底获得博士学位。2015年在德克萨斯大学奥斯汀分校进行博士后研究。2016年至2020年在斯坦福大学进行博士后研究工作。2020年12月入职南方科技大学,任助理教授。

从事计算力学,流固耦合,生物力学等领域的研究。学术成果包括:

(1)发展了汽液相变的连续介质模型。基于此模型开发了保结构且非线性稳定的有限元计算格式以及并行计算软件。相关成果为理解蒸发,沸腾,凝固等相变现象提供了理论和计算基础。

(2)构造了描述流固耦合的统一框架。为非线性不可压的大形变固体力学以及其和流体力学的耦合提供了一整套简洁的建模和计算方案。该方法可简化现有的强耦合的计算方案,并且对于解决计算固体力学的遗留问题提供了新的思路。该方法可有效地计算弹性和非弹性材料在不可压约束条件下的机械性能,并且可以对结构失稳提供更稳健的预测格式。
