The Main Idea
Ductility is a solids ability to deform under tensile stress. It is similar to malleability, which characterizes a materials ability to deform under an applied stress. Ductility is an important property in material science and metal-working industries, where solids are deformed nd molded with outside forces.
A Mathematical Model
Mathematically, ductility can be defined as the fracture strain, or the tensile strain along one axis that causes a fracture to occur. Fractures range from brittle fractures to fully ductile fractures, resulting in very different physical appearances associated with the different types.

History
Percy Williams Bridgman's findings on tensile strength and material properties led to much of what is known about ductility, including that it is highly influenced by temperature and pressure. these findings led him to win the 1946 Nobel Prize in physics.
