With the aim to fully understand the essence of material strength and various physical properties, our group performs numerical simulations such as classical molecular dynamics and ab initio (first-principles) density functional method calculations to clarify materials behavior at the nano and micrometer scales. In addition, we work on multiscale mechanical simulations based on the knowledge of nano and microscale phenomena. Our research topics include analysis of ideal strength, deformation, fracture and structural instability modes of crystalline materials, buckling deformation and multiphysics of low-dimensional nanostructures, coarse-grained molecular dynamics study of boundary lubrication, reaction molecular dynamics simulation of chemical mechanical polishing, multiscale analysis of deformation and fracture of polymer materials, and machine-learning based multiscale simulation model construction for nano-micro fatigue, etc.
