N2 - Previous research has shown the importance of flaws for the fatigue life of elastomers. However, there are other factors that may limit fatigue life apart from flaw size such as their numbers per volume, their distribution and the flaw density. This research aims to establish the use of an effective flaw size to bring together the fracture mechanics approach and fatigue life simulation for complex filled industrial style elastomers. Fatigue data and fracture mechanics are used to calculate a representative Effective Flaw Size (EFS) which allows the calculation of fatigue properties of commercial filled elastomers that are inhomogeneous by nature. The Effective Flaw Size in combination with a stress concentration factor and dynamic strain energy can as well be used to simulate the fatigue behaviour under non-relaxing conditions. Until now the fracture mechanics approach did not work for the calculation of fatigue life when minimum loads, especially in tension were applied.
