Tensile Strength, the maximum force developed a test specimen before rupture on the tensile test carried to rupture under prescribed conditions. Tensile Strength (as used here) is the force per unit width of test specimen. Stretch, the maximum tensile strain developed in the test specimen before ruptrure in a tensile test carried to rupture under prescribed conditions. The stretch (or percentage elongation) is expressed in a percentage i.e. one hundred times the ratio of the increase in length of the test specimen to the original test span.
Tensile energy absorption (TEA), the work done when the specimen is stressed to rupture in tension under prescribed conditions as measured by the integral of the tensile strength over the range of tensile strain from zero to maximum strain. The TEA is expressed as energy per unit area (test sapn X width) of test specimen.
Breaking Length, the calculating limiting length of strip of uniform width, beyond which, if sucha strip were suspended by one end, it would break of its own weight.
Tensile Index, the tensile strength in N/m divided by grammage.
