What is meant by ductile?
	Ductility is a measure of the degree of plastic deformation that is sustained at fracture l ductility is measured using % elongation l %EL = 100*(lf – lo)/lo l if %EL >5%, material is considered ductile l lf = fracture length of test specimen l lo = original gauge length of test specimen If a material does not experience much plastic deformation at fracture, the material is called brittle
