Calculation method
Calculation method
Miner linear damage index
Sum n/N for entered cycle counts and fatigue lives; 1−damage is a linear-model margin, not guaranteed remaining life.
Remaining linear damage fraction
Sum n/N for entered cycle counts and fatigue lives; 1−damage is a linear-model margin, not guaranteed remaining life.
Symbols and units
- a
- Applied cycles by stress range (counts)
- b
- User-supplied cycles to failure (counts)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Sum n/N for entered cycle counts and fatigue lives; 1−damage is a linear-model margin, not guaranteed remaining life. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
