Qualitative Results
The qualitative results of the impact test can be used to determine the ductility of a material. If the material breaks on a flat plane, the fracture was brittle, and if the material breaks with jagged edges or shear lips, then the fracture was ductile. Usually a material does not break in just one way or the other, and thus comparing the jagged to flat surface areas of the fracture will give an estimate of the percentage of ductile and brittle fracture.

Famous quotes containing the words qualitative and/or results:
“You ask: What is it that philosophers have called qualitative states? I answer, only half in jest: As Louis Armstrong is said to have said when asked what jazz is, ‘If you got to ask, you ain’t never gonna get to know.’”
—Ned Block (b. 1942)
“In the works of man, everything is as poor as its author; vision is confined, means are limited, scope is restricted, movements are labored, and results are humdrum.”
—Joseph De Maistre (1753–1821)
