Cyclic Stress: Fatigue SpringerLink
Cyclic stress is the distribution of forces (aka stresses) that change over time in a repetitive fashion. As an example, consider one of the large wheels used to drive an aerial lift such as a ski lift. The wire cable wrapped around the wheel exerts a downward force on the wheel and the drive shaft supporting the … See more Cyclic stress is frequently encountered in rotating machinery where a bending moment is applied to a rotating part. This is called a cyclic bending stress and the aerial lift above is a good example. However, cyclic See more When cyclic stresses are applied to a material, even though the stresses do not cause plastic deformation, the material may fail due to fatigue. Fatigue failure is typically modeled by decomposing cyclic stresses into mean and alternating components. Mean … See more WebLow-cycle fatigue (LCF) is characterized by its high stress amplitude and low frequency. In this case, stress produces both elastic and plastic strains. The latter is particularly important in areas with geometric discontinuities or stress risers. horry county personal property form pt-100
