The dimensioning of injection heads for the extrusion of rubber profiles is exclusively based on empiric knowledge of the non-linear viscoelastic flow behavior of elastomers especially of the so-called die swell. Thus, the design of injection heads is carried out with subject to the used rubber blend, whereas the geometry of the appropriate profile is(More)
Loading parameters (frequency, amplitude ratio and waveform) are varied to determine their influence on fatigue crack growth in rubber. Up to three different rubber blends are investigated: one actual engineering material and two model materials. Fatigue crack growth curves and strain distributions of pure shear and faint waist pure shear samples are(More)
