Torsion Overload
Torsion OverloadThe stress state associated with pure torsion was described in Chap. 2. In cylinders the maximum normal stress is at 45° to the axis, and the maximum shear stress is at 90°. Fracture can occur in a ductile or in a brittle manner. If the material fails in a ductile fashion, then obvious plastic deformation will be detected. For example, if the cylinder has axial marks on the surface (such as drawing lines), then these will be spiraled around the surface. A clear example is shown in Fig. 4.16. A case showing twisted splines which reveal torsion fracture is illustrated in
