Stress-Strain Curves A tensile test involves mounting the specimenin a machine, such as those described in the pre-vious section, and subjecting it to tension. Thetensile force is recorded as a function of the in-crease in gage length. Figure 4(a) shows a typ-ical curve for a ductile material.
Ductility is the percent elongation reported in a tensile test is defined as the maximum elongation of the gage length divided by the original gage length. The measurement is determined as shown in Figure 6. Reduction of area is the proportional reduction of the cross-sectional area of a tensile test piece at the plane of fracture measured after fracture. The reduction of area is reported as additional information (to the percent elongation) on the deformational characteristics of the material. The two are used as indicators of ductility, the ability of a material to be elongated in tension. Because the elongation is not uniform over the entire gage length and is greatest at the center of the neck, the percent elongation is not an absolute measure of ductility.
