TORSION FUNDAMENTALS 2.1 Shear Center The shear center is the point through which the applied loads must pass to produce bending w ithout twisting. If a shape has a line of symmetry, the shear center will always lie on that line; for cross-sections with two lines of symmetry, the shear center is at the intersection of those lines (as is the ...

Extension & Torsion Springs (Chapter 10)

faculty.mercer.edu

Stress in Torsion Springs The coil of a torsion spring experiences bending stress (despite the name of the spring). Including a stress-correction factor, the stress in the coil can be represented by The stress-correction factor at inner and outer fibers has been found analytically for round wire to be K i is always larger, giving the highest stress at the inner fiber.

Torsion: When we look at the end constraint (e.g., rod attached at boundary): Figure 12.13 Overall view of rod under torsion Here, St. Venant theory is good in this local region, violation of assumption of St. Venant theory Built-in end At the base, w = 0. This is a violation of the “ free to warp ” assumption. Thus, σ zz will be present. ⇒
