Web25 nov. 2014 · The transition between the low- and high-cycle fatigue varies, but is usually somewhere in the span of 1,000 to 10,000 cycles. Non-Proportional Loading The challenge for non-proportional loading is to determine the range of the fatigue-controlling parameter. WebFatigue has been separated into regions of high cycle fatigue and low cycle fatigue. The chief difference between high cycle and low cycle fatigue is the number of cycles to failure. Transition between LCF and HCF is determined by the stress level, i.e. transition between plastic and elastic deformations. Webstress and the high stress will be repeated during the reactor operation. Since the repeated stress level would be high, the low cycle fatigue design would be required. The low cycle fatigue design needs the fatigue life data which is a fatigue life diagram between a strain range and a fatigue life.

WebLow cycle fatigueis characterized by repeated plastic deformation (i.e. in each cycle) and therefore, the number of cycles to failure is low. In the plastic region large … WebLow cycle fatigue This is mainly applicable for short-lived devices where very large overloads may occur at low cycles. Typical examples include the elements of control systems in mechanical devices. A fatigue failure mostly begins at a local discontinuity and when the stress at the discontinuity exceeds elastic limit there is plastic strain.
