Ductility 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.The ductility of steel varies depending on the alloying constituents.his 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.

Spacer Bras â New Technology in Bras. When shopping for bras you might be lucky to hear a term âSpacer Braâ, which became an excellent alternative to the seamless ât-shirt brasâ. These spacer bras is not available in many stores yet because it is a totally new technology in bra design â âair pocket technologyâ. The issue with the bras that are widely available in your local stores small or big is that the bras are made of fabrics or sheer mesh.
