Initial Tensile Behaviour of Elastomers

Popis výsledku v původním jazyce

At very small strains the tensile stress-strain relationship of elastomers is often fairly linear and therefore might be used for obtaining initial tensile modulus E. In this work we analysed initial tensile data of unfilled and carbon black filled vulcanised SBR samples to test if it is feasible. Strains from a mechanical contact extensometer data have shown that the initial stress-strain dependence is nearly linear as expected but does not go through origin probably because of random initial time lagbetween force and extension times at zero crossing. Initial strains from crosshead positions have lower variation coefficients than initial strains from the mechanical contact extensometer data and, consequently, also initial tensile modulus from crosshead positions has lower variation coefficients than initial tensile modulus from the mechanical contact extensometer data.
