The enduring nature of a rivet’s fastening arises from the plastic deformation of its shank. Initially, the rivet is inserted through aligned holes in the materials being joined. Subsequently, the protruding end is deformed, typically by hammering or pressing, to create a head. This process expands the shank within the hole and tightly clamps the materials together. This deformation is irreversible, meaning the rivet cannot return to its original shape and be easily removed without damage.
This fastening method offers high shear and tensile strength, making it suitable for applications where structural integrity is paramount. Its reliability has been proven over centuries, finding use in bridge construction, aircraft manufacturing, and shipbuilding. The resulting joint is resistant to vibration and loosening, crucial in dynamic environments. The permanence also reduces the risk of tampering or unauthorized disassembly, adding a security element in certain applications.
