Tensile Test to Determine the Tensile Strength and Elongation at Fracture

The tensile test is the most important testing method in destructive materials testing. A standardized specimen with a known cross section is loaded uniformly with relatively low increasing force in the longitudinal direction. A uni-axial stress state prevails in the specimen until contraction commences.

The ratio of stress to strain can be shown from the plotted load-extension diagram.
