摘要：
The paper deals with the application of fracture mechanical methods for the characterisation of crack toughness behaviour of mainly filler-reinforced elastomeric materials. The reliability of the experimental methods regarding a reproducible determination of geometry-independent fracture mechanical values is discussed. Furthermore, possibilities of a quantitative assessment of the connection between structural parameters such as filler content and fracture mechanical values are shown by using some examples. On the basis of the experimental results, a model for crack initiation and propagation behaviour of non-crystallising elastomers was proposed and is shown in detail.
