Definition of Ductility and Malleability in terms of Mechanical Engineering.

Simple definition of ductility is the property of a material to form wires and that for malleability it is said that it is the property of a material to form sheets.

But in Mechanical Engineering, we need to be more specific.

A material which can withstand tensile load condition under considerable  deformation without breaking is called Ductile material and that property is called Ductility.

A material which can withstand compressive loads under considerable deformation without breaking is called Malleable material and that property is called Malleability.
