ABSTRACT
Investigation of the molecular mobility of polymer chains and networks under large static deformations is one of the important topics in the modern physics of rubbers. On the one hand, superposition of large static and small oscillating strains has been proposed recently as a method for studying the molecular mobility and structure of polymer networks (Bodneva, Borodin, Khazanovich 2005; Munch, Pelletier, et al. 2006). On the other hand, this topic is of importance to understand the phenomenon of crack propagation in heterogeneous rubbers under pulsed loading conditions (Horst and Heinrich 2008; see also https://www.ipfdd.de/FOR597).
