What are cyclic loads?
  • A
    Static reversible loads.
  • B
    Static irreversible loads.
  • C
    Dynamic reversible loads.
  • D
    Dynamic irreversible loads.
Cyclic loading is the application of repeated or fluctuating stresses, strains, or stress intensities to locations on structural components. For instance, a cyclic load may be on the fuselage on each landing as a result of the impact on touchdown or the forces arising on the wings because of gusts in flight. The degradation that may occur at the location is referred to as fatigue degradation or failure. Cyclic load is a dynamic load and the direction of loads changes during the life cycle of a structure therefore it is a reversible load.
