报告摘要：
Atomistic modeling based on electronic and atomic structure calculations is one of the most promising ways to reveal and predict the mechanical properties of structural materials, along with recent atomistic scale experimental observation techniques and multiscale modeling techniques. Here I introduce several our recent atomistic analyses for understanding and predicting the mechanical properties of structural materials. The talk may include the following topics. (1) atomistic prediction of Si solute atom effect on yield stress of Fe-Si alloy. (2) interstitial carbon and hydrogen diffusion behaviors in defective BCC iron and its effects on dislocation motion. (3) creep deformation of bulk nanostructured metal. (4) accelerated molecular dynamics simulations of GB diffusion, dislocation nucleation from GB, GB sliding and migration at finite temperature and usual stress levels. (5) first-principles study of deformation twining process in Mg.
