研究兴趣

应用力学方法旨在通过近似模型和数值方法有效解决工程科学中的实际应用问题,基于经验化本构关系和有限元数值模拟的应用力学模型已广泛用于预测宏观复杂结构材料的静动态响应。本小组致力于从应用力学与工程的观点研究微结构力学中的核心问题:微结构-工艺过程-性质的关联。课题组主要研究材料中的应力与变形和材料微细观结构单元耦合演化过程的关联特性,揭示材料中的各种应力驱动不稳定性起源、复杂失效机制等非线性、非平衡力学现象,深入理解材料微结构-性能关系,进而剪裁细观结构,设计高性能材料。我们拟通过借鉴凝聚态物理中相变、非线性动力学等概念扩展细观力学,发展材料微结构力学模型,结合多尺度数值计算和实验验证的手段评估、预测和设计材料的微结构演化以及微结构依赖的力电磁等宏观物理性质(本构关系),以期为定量化的材料微结构设计与性能优化研究提供思路和指导。
