WebElongation at break, also known as fracture strain, is the ratio between changed length and initial length after breakage of the test specimen. It expresses the capability of natural plant fiber to resist changes of shape without crack formation. The elongation at break can be determined by tensile testing in accordance with EN ISO 527. WebFigure 1: Engineering stress-strain curve from which mechanical properties are derived. The elongation at which the load maximum occurs is known as Uniform Elongation. In a tensile test, uniform elongation is the percentage the gauge length elongated at peak load relative to the initial gauge length.
