研究领域

1. 微纳米尺度下极端制造过程中的关键力学问题

建立描述低维构筑单元,如二维材料、纳米银片等在纳米尺度下构筑为三维复合结构,如多孔球,薄膜等过程中力学行为的理论模型,用于指导制造工艺的优化和产物的调控,并运用数值模拟技术,如分子动力学、有限元分析等对力学模型进行对比验证。

2. 二维材料中应变场与量子性能的精确调控

建立“应力源”与二维材料间载荷传递的力学模型,并发展可精确复现“应力源”与二维材料间相互作用的数值模拟方法,实现基于“应力源”方法的二维材料中应变场的精确调控,以及按照特定量子性能,如赝磁场分布,的反向“应力源”设计。

3. 低维材料复合结构的力学性能及其导热性能调控

建立描述低维材料复合结构在力学载荷下单体变形与整体组装形态演化的力学模型,并结合声子导热模型,预测并调控其在力学载荷下的导热性能,同时,结合机器学习,实现复杂结构的导热性能预测。

4. 大尺度、高效率、高精度的分子动力学模拟方法

通过理论比拟、粗粒化建模、等效力场等手段,实现兼顾精度和效率的大尺度分子动力学模拟,将分子动力学模拟的空间尺度拓展到微米级,时间尺度拓展到微秒级。相比于传统全原子分子动力学方法,实现至少三个数量级的计算效率提升。
