Helical wire stress

Web23 nov. 2016 · 21. A round wire helical compression is subjected to axial force. The effect of axial force is equivalent to: 1. Torsional T=FD/2, acting on the wire cross section 2. Direct shear force F acting on wire cross section So stresses induced in spring wire are, 1. Torsional shear stress 2. Direct shear stress 21 22. 1. Web7 apr. 2024 · The stress at the critical point of the helical wire is investigated based on the model by considering the local flexure. The results indicate that the present model can well simulate the bending stiffness variation during irregular response, which has significant effect on the stress of helical wire.
