ductility

[duktil′itē]
the property of a material of having a large elastic range and tending to deform before failing from stress.

ductility (duktil´itē),

n the property of a material that allows permanent deformation under tension without rupture. It is measured as a percentage increase in length on rupture compared with original length and is termed percentage elongation, or elongation.
