Ermüdungslebens
Ermüdungslebens, a term derived from German, translates to "fatigue life" in English. It refers to the number of stress cycles a material can withstand before it fails due to fatigue. Fatigue is a phenomenon where a material weakens and eventually fractures under repeated or fluctuating loads, even if the stress levels are well below the material's ultimate tensile strength.
The concept of fatigue life is crucial in engineering, particularly in the design of structures and components
Factors influencing fatigue life include the magnitude and nature of the applied stress (e.g., tension, compression,
Engineers use various methods to estimate and predict fatigue life, including S-N curves (stress-life curves) which
