A new fatigue testing machine for accurate crack growth analysis in rubber compounds

von Arnaud Favier

The resistance to tearing is a key factor for elastomers in many applications: (tyre tread, dampers, etc.). 01dB-Metravib (Dynamic Mechanical Analysis instrument manufacturer), enlarges its range of elastomer testing products by introducing a new machine: DMA+300.

This instrument is specifically designed for fatigue and crack growth tests analysis on elastomers and allows controlling different parameters such as the temperature, the oxygen environment, the frequency of excitation, the amplitude of excitation, and the excitation waveform.
This paper presents this instrument and its capabilities.
