<P> Ductility is a measure of a material 's ability to undergo significant plastic deformation before rupture , which may be expressed as percent elongation or percent area reduction from a tensile test . According to Shigley 's Mechanical Engineering Design -- 10th Ed . significant denotes about 5.0 percent elongation ( Section 5.3 , p. 233 ) . See also Eq. 2 - 12 , p. 50 for definitions of percent elongation and percent area reduction . Ductility is often characterized by the material 's ability to be stretched into a wire . </P>
