Some definitions using in Engineering materials
Stiffness- The ability of a material to resist deformation under stress. The Modulus of Elasticity elasticity is the measures of stiffness.
Elasticity- It is the property of a material to regain its original shape after deformation when the external forces are removed. The steel is more elastic than rubber.
Ductility- It is the property of a material enabling it to be drawn into wire with the application of a tensile force. Ductile material commonly used in Engineering Practice are mild steel, copper, aluminum, nickel, zinc, tin and lead.
Brittleness- It the property of a material opposite to ductility. It is the property of breaking a material with little permanent distortion. Cast Iron (CI) is a brittle material.
