Miner’s Rule

Miner’s Rule is a method used in engineering to predict the fatigue life of a material subjected to repeated loads. It assumes that each load cycle contributes a measurable amount of damage to the material, and the total damage accumulates over time. By summing the ratios of applied cycles to the number of cycles the material can withstand at each load level, engineers estimate when the material will reach its failure point. If the total damage sum reaches 1, failure is expected. This approach helps in designing components that can endure varying loads without premature failure.
