Quantitative Relations Among Measures of Ductility in Planar and Through-Thickness Tension Tests of 12.8-mm-Diameter Specimens
The distribution exponent (DE) is a measure of a material's ability to transfer its inherent ultimate ductility (as measured by reduction of area RA) into practical maximum extension in the direction of forming forces (as measured by elongation, in 50.8 mm [2 in.], EL). The computation, nature, and utility of the distribution exponent are discussed herein.
