Mechanical Properties
Strength
Plasticity
Elasticity
Ductility
Hardness
Malleability
Strength
Strength is the ability to resist a force without breaking
Tensile
Compressive
Shear
Plasticity
The readiness to deform to a stretched state when a load is applied
Elasticity
The ability of a material to return to it’s original shape when deformed
Ductility
The ability of a material to be drawn out into a wire
Depends on the plasticity and tensile strength of the object.
Hardness
The resistance to wear of a material
Measured on the Mohs scale
Malleability
The ability of a material to be pounded flat
Creep
Slow plastic deformation that occurs when a load is applied over long periods.
Fatigue
When a load applied many times is enough to cause a failure even though a single instance is not enough
Resilience
The ability of a material to absorb energy on deformation
Toughness
The ability of a material to withstand a sudden force.
Brittleness
The lack of toughness or tensile strength
