Test Method Title
Test Method for Tensile Properties of Geotextiles by the Wide-Width Strip Method
tensile strength, elongation, tensile modulus
Description of Test
An 8" wide specimen is gripped across its entire width in the clamps of a constant rate of extension (CRE) type tensile testing machine operated at a prescribed rate of extension applying a longitudinal force to the specimen until the specimen ruptures. Tensile strength, elongation, initial and secant modulus, and breaking toughness of the test specimen can be calculated from machine scales, dials, recording charts, or an interfaced computer.
