The Versatility of Galvanized Chicken Wire Mesh

The maximum tensile beam stresses are located on the OD when the spring is subject to windup deflections; conversely, the stresses on the ID are at maximum compression. When the spring is subject to unwind, the stresses are the opposite. It is critical that there be no nicks or cuts at the area where the stresses are at maximum. These flaws would increase the stresses, and possibly initiate cracks. For the same reason, machined torsional springs should contain stress relief holes or slots to help mitigate “stress risers” as the coil section changes into the solid structural section of the spring end.
