Simulation of partially reversible networks under deformation or swelling — •Toni Müller^1,2, Jens-Uwe Sommer^1,2, and Michael Lang¹ — ¹Leibniz Institut für Polymerforschung Dresden, Hohe Straße 6, 01069 Dresden, Germany — ²Institute of Theoretical Physics, Technische Universität Dresden, Zellescher Weg 17, 01062 Dresden, Germany

Self-healing and partially reversible networks are interesting elastic materials that self-repair damage [1] and can be used to optimize energy dissipation [2]. Using the bond fluctuation model, we study networks made of varying fractions of reversible and irreversible bonds and investigate the molecular mechanism of bond breaking and rearrangement under uni-axial extension or swelling. One goal is to better understand the influences of the fracture energy and sticker density to optimize the properties of such materials.
