10- ASTM E8—Tension Testing of Metallic Materials

Purpose: ■ To determine stress–strain relationship ■ To determine yield strength ■ To determine tensile strength ■ To determine elongation and reduction of cross-sectional area ■ To determine modulus of elasticity ■ To determine rupture strength Significance and Use: This test provides information on strength and ductility for metals subjected to a uniaxial tensile stress. This information may be useful in comparison of materials, alloy developments, quality control, design under certain circumstances, and detecting nonuniformity and imperfections, as indicated by the fracture surface.
