Investigation of strain induced crystallization of natural rubber under cyclic impact loading — •Konrad Schneider — Leibniz-Institut für Polymerforschung Dresden, Hohe Str. 6, 01069 Dresden, Germany

Strain induced crystallization (SIC) is one of the special features of natural rubber (NR), responsible for its outstanding mechanical performance. Nevertheless, for short term behaviour of NR, e.g. within a rolling tire, the dynamic of SIC plays an important role. By means of synchrotron x-ray scattering SIC is monitored during impact loading together with recording energy dissipation by thermography. The results enable a more realistic modelling of the dynamic behaviour of natural rubber.
