Investigating dynamic interactions by multi-scale modelling: From theory to applications

The wish to design novel materials by profiting from computational tools and experimental techniques brought significant requirements of finding bridges between system scales relevant for understanding the different scales mechanisms which influence the resulting material application performance. Using multi-scale approaches system dynamics can be accessed, while a lot of experimental measurements are performed ex situ characterizing a sample state at fixed time. In this chapter, mechanisms and phenomena investigated for materials design illustrate advances obtained by multi-scale modelling and contributing to a closer relationship between experiments and theory when facing challenges related to understanding a system dynamically interacting with its environment.
