What is Metal Strength?
Metal strength is a measure of a material's ability to withstand an applied force without failure or plastic deformation. The strength of a metal is influenced by several factors, including its atomic structure, composition, and the presence of impurities. The primary types of strength that are commonly assessed include:
- Tensile Strength: The maximum amount of tensile (pulling) stress that a material can withstand before failure.
- Compressive Strength: The capacity of a material to withstand axial loads that tend to reduce its size.
- Yield Strength: The stress at which a material begins to deform plastically.
- Shear Strength: The ability of a material to resist shear forces.
