Indeed, when one of the failed springs was examined for the presence of residual tensile stress, fairly high stresses were found. Failure...

If a shaft loaded in torsion is assumed to consist of an infinite number of infinitely thin disks that slip slightly with respect to each other under the torsional stress, visualization of deformation is simplified. Torsional single-overload fracture of a ductile material usually occurs on the transverse...
