Abstract
|
Viscoelastic properties, micro-mechanical material parameters and fatigue crack propagation rates of a series of rubber samples, based on high vinyl S-SBR and EPDM with variable type (carbon black and silica), activity and amount of filler, have been investigated (Tab. 1). Relaxation time spectra are evaluated for describing the visco-elastic crack opening mechanism. The predicted power law exponents of fatigue crack propagation rates agree fairly well with measurements at moderate severity (harmonic loading, 4 Hz). The dependence of the filler network parameters correlates qualitatively with the behaviour of the tear resistance obtained under high severity conditions (pulsed loading, 50 ms, 10 Hz).<br /><br />Proceedings: Euromech 502 Colloquium, Dresden 8.-10.
