| Description
| - The present work proposes a new fracture mechanical testing concept for determination of dynamic crack propagation of rubber materials. This concept implements a method of simultaneous tensile- and pure-shear-mode testing. The present approach is based on an upgrade of the Tear Analyzers (Co. Coesfeld GmbH), on the fracture mechanics theory of dynamically loaded test specimens and on the definition of pure-shear states according to the test specimen’s geometry ratio. The main focus of this work can be divided in three parts. Firstly it is introduced the development of a method for analysis of dynamic crack propagation in filled rubber by simultaneous tensile- and pure shear mode testing. The servo-hydraulic machine with controlled temperature testing chamber is equipped with simultaneously operating two mode test equipment which represents a new fracture testing method. Secondary this work deals with the development of a method for a defined creation of a notch in a rubber specimen. This method serves as a basis for the reproducible and reliable determination of fracture mechanical parameters for elastomers. After insertion of notches in a defined way, fracture tests under different loading conditions were performed. A significant influence of the notch geometry on the test results was observed. Next the analysis of crack propagation under the dynamic loading conditions is practised with this method. It is shown how the tearing energy and the crack growth rate depend on the test specimen’s geometry ratio and crack length. It is also demonstrated that the values for tearing energies and also crack growth rates for short crack lengths in SENT- as well as in pure-shear test specimens are identical. Another important aspect is related to the different values of tearing energies and crack growth rates for cracks with short and large lengths in pure-shear test specimens.
