Engineering Fundamentals Refresh:Strength vs. Stiffness

Fracture strength is the value corresponding to the stress at which total failure occurs. Stiffness is how a component resists elastic deformation when a load is applied. Hardness is resistance to localized surface deformation. The strength of a material can refer to yield strength, ultimate strength, or fracture strength.

Material Strengthening Mechanisms

Strengthening The ability of a metal to deform plastically depends on the ability of dislocations to move. Hardness and strength are related to how easily a metal plastically deforms, so, by reducing dislocation movement, the mechanical strength can be improved.
