| contents | We carry out uniaxial continuous and step stretching of various crosslinked polymer networks to demonstrate how characteristics of rupture (from continuous stretching) and delayed rupture (from step stretching) can be used to probe the structure of the emergent kinetic theory of bond dissociation (KTBD) for elastomeric failure. Based on delayed rupture experiments, we show that the network lifetime tntw, taken as the incubation time for delayed rupture, depends on temperature in an Arrhenius like manner and is exponentially sensitive to the degree of network stretching (depicted by step-stretch ratio ). Rupture during continuous stretching for a wide range of stretch rates takes place on timescales inversely proportional to the stretch rate. The elapsed time at rupture is found to be comparable to at various values of L/L0b = L/L0ss in a wide range of temperature, affording the experimental basis for the premise of the KTBD. Having identified the hidden internal clock , continuous stretching tests at different temperatures are performed to show the existence of a new time temperature equivalence (TTE): fast stretching at higher temperatures is equivalent to slow stretching at lower temperatures: different pairs of rate and temperature can produce the rupture at the same tensile strength and strain. |
