Sebastian Pfaller achieved his doctorate (degree Dr.-Ing.) in 2015 with the doctoral thesis entitled “Multiscale Simulation of Polymers”. He is head of the Capriccio group, which he established in 2018 at the Chair of Applied Mechanics at the Friedrich-Alexander-Universität Erlangen-Nürnberg. His research interests comprise multiscale simulation of polymers, continuum descriptions of particle-based systems, and interphase effects in polymer nanocomposites.

Abstract:
Classical continuum approaches do not explicitly consider the specific atomistic or molecular structure of materials. Thus, they are not well suited to describe properly highly multiscale phenomena as for instance crack propagation or interphase effects in polymer materials. To integrate the atomistic level of resolution, the “Capriccio” method has been developed as a novel multiscale technique and is employed to study e.g. the impact of nano-scaled filler particles on the mechanical properties of polymer-nanocomposites. Further research activities focus on adaptive particle-based regions moving within the continuum, which is essential for multiscale simulation of crack propagation.
