Definition

A time‑domain cycle‑counting algorithm that reduces a complex, irregular uniaxial stress or strain history to a set of elementary closed and half cycles (amplitude and mean) suitable for cumulative fatigue damage evaluation, typically used together with S–N or strain‑life data and a linear damage summation rule (e.g., Palmgren–Miner).
