Fatigue testing – High Cycle Fatigue domain

fatigue; tiredness

Progressive failure of a specimen or structure subjected to cyclic loading, leading to failure.

High Cycle Fatigue (HCF)

This is a field where service lives are generally between 50,000 and several million cycles, and where the stress remains mostly below the material's elastic limit. Tests are stress-controlled.

oligocyclic fatigue; Low Cycle Fatigue (LCF)

A field where service lives are generally between a few hundred and a few million cycles, and where the load is mostly above the material's elastic limit. Tests are deformation-controlled.

gigacyclic fatigue; gigacyclic fatigue

Where service lives range from several million to several billion cycles, and where the stress is far below the material's...
