what is ductility in a solid
This tensile test of a nodular cast iron demonstrates low ductility. In materials science, ductility is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into a wire.uctility can be quantified by the fracture strain, which is the engineering strain at which a test specimen fractures during a uniaxial tensile test. Another commonly used measure is the reduction of area at fracture.
