number of cycles

The number of load cycles indicates how often a material has been loaded under the same stress. It helps determine the service life of components.

Physicochemical Mechanism of Action

Fatigue life counts the number of repeated loads a material undergoes. Each cycle causes microscopic damage that accumulates.

Metallurgical Relevance & Welding Risks

Too high a load cycle count can lead to fatigue and fracture of the material. This is especially relevant for components under high stress, such as in machinery or aircraft.

Workshop Practice & Actions

For lifetime determination, fatigue life is measured with maximum stress or force. Example: A material can withstand 10^6 load cycles at a stress of 200 MPa before it breaks.
