Home > Elastomer Properties > Tensile Stress Elastomer Properties  Tensile Stress/StrainTensile strength is the maximum tensile stress reached in stretching a test piece (either an Oring or dumbbell). Elongation: The strain, or ultimate elongation, is the amount of stretch at the moment of break. Modulus: Also called “Mod 100,” this is the stress required to produce a given elongation. In the case of “Mod 100,” the modulus would be the stress required to elongate the sample 100%. In elastomers, the stress is not linear with strain. Therefore the modulus is neither a ratio nor a constant slope—but rather denotes a point on the stressstrain curve. Tensile tests are used for controlling product quality and for determining the effect of chemical or thermal exposure or an elastomer. In the latter case, it is the retention of these physical properties, rather than the absolute values of the tensile stress, elongation or modulus, that is significant. Test Methods:
