Understanding Flexural and Tensile Moduli of Small Drawn Wires

Many mechanical components as springs, use small mechanical drawn wires. Small drawn wires undergo manufacturing processes that alter their mechanical properties. While manufacturers often designate distinct elastic moduli for tension and bending in wires smaller than one millimeter, scientific consensus recognizes the Young modulus as the fundamental measure. This study aims to elucidate the drawing process and bending mechanisms, explaining why wires might exhibit lower stiffness than anticipated via the common Young modulus, leading to the prevalent use of a specialized elastic modulus in bending.
