See examples of ductile … WebThere are two measures required when calculating ductility: Elongation The increase in the gage length of the material, being subjected to tensile forces, divided by the original gage length. The elongation is often expressed as a percentage of the original gage length. Use the following formula to calculate elongation: Elongation (%) = 100 x ∆L/Lo
WebDuctility may be expressed as percent elongation or percent area reduction from a tensile test. ... Ductility may also be thought of in terms of bendability and crushability. Usually, if two materials have the same strength and hardness, the one that has the higher ductility is more desirable. The ductility of many metals can change if ...
