Study on multi-scale modeling of plasticity by atomic model

By virtue of the development of metallurgy and the theory of dislocation, one can qualitatively anticipate the mechanical properties of a material from its microstructure. Moreover, not qualitative but quantitative and precise anticipation is more beneficial for efficient development of new materials. In this context, we utilize a multi-scale method with atomic model, which is a particle system that has potential, and discuss the possibility of quantitative anticipation of material properties including plastic deformation through several representative numerical examples.
