Summary edit
DescriptionMetalFatigue 006.jpg | A cross section of a spring that failed in the NBS study shows a fatigue crack which developed along longitudinal planes in the wire. The section is some distance from the fracture. The study showed that initial fatigue failure of the compression springs occurs on longitudinal planes of mazimum shear stress in the wire. (1) The crach progresses for some distance along the wire before a crack normal to the tensile stress is started. (x 50). (2) Typical fracture of helical compression spring wound from music spring wire. Arrow A indicates plane of tensile fatigue cracks. Arrows from B indicate surface of longitudinal shear crack. | ||||
