Welcome to Shibutani LAB.
Introduction of Research Group
Any material consists of atoms or molecules. When it deforms under some external loading, no one can look over both the globally continuous and the atomic-level deformation behaviors. Multiscale Modeling (MM) aims at linkage between the two over the vast time and scale gap. We have researched the computational MM including the ab-initio calculations and atomistic simulations, and also the experiments using nanoindentation.
To discover the novel an optimum structure with size effects of the mechanical behaviors, the new optimization technique combined with finite element method (FEM) has been developed. Additionally, we have tackled accurately measuring mechanical properties with timbre of solid material: Resonance Ultrasound Spectroscopy (RUS). We are also extending the mechanics to the social problems like the risk analyses and also the dental problems.
