..., which are simplified models of complex stress systems. Free-body diagrams of shafts in the pure types of loading (tension, torsion, and compression) are the simplest; they then can be related to more complex types of loading. This chapter discusses the principles of these simplest loading systems...

.... The fractographic features of the shaft are clear indications of torsional failure. The universal links at the ball ends showed wear marks as evidence of torsional loading in one direction. From the damage features observed, it is concluded that the cardon shaft failed under torsional overload. Because...

...) Transverse hole stress concentration A cylindrical shaft under pure torsional loading (twisting) has stresses that are maximum at the surface and zero at the center or neutral axis of the shaft, as shown in Fig. 2(a) . Pure torsion loading of a cylindrical shaft causes all stress components—tension...

Examples of sudden onset deformation are buckling instability in compression of columns or torsion of tubes. A roof truss that collapses under a snow load is such an example. Roof trusses are not usually...

It is most common when long, slender columns are compressed in an axial direction, or when thin-wall tubes are compressed in either an axial direction or a diagonal direction as a result of torsional loading. This type of failure also can occur on the compressive...
