Abstract
The objective of the research presented in this paper is to investigate the influence of glass spheres as model flaws on the fatigue to failure and crack propagation properties of rubber materials. A second objective was to predict fatigue to failure properties with fracture mechanics calculations based on crack propagation properties and to compare these with experimental observations. Glass spheres of different sizes were added to an EPDM material for this purpose. The glass spheres reduced the fatigue to failure properties of the EPDM material considerably depending on the size of the spheres. Crack propagation properties were influenced to a minor extent. Fracture mechanics calculations with known initial flaw (glass sphere) sizes resulted in good to excellent correlation with fatigue to failure experiments.
