Cumulative Damage and Life Prediction Models for High-Cycle Fatigue of Metals: A Review

Fatigue design of engineering structures is typically based on lifetime calculation using a cumulative damage law. The linear damage rule by Miner is the universal standard for fatigue design even though numerous experimental studies have shown its deficiencies and possible non-conservative outcomes. In an effort to overcome these deficiencies, many nonlinear cumulative damage models and life prediction models have been developed since; however, none of them have found wide acceptance. This review article aims to provide a comprehensive overview of the state-of-the art in cumulative damage and lifetime prediction models for endurance based high-cycle fatigue design of metal structures.

Automated summary

Fatigue design of engineering structures is often done based on cumulative damage law, with Miner's linear damage rule being the standard despite known deficiencies. Nonlinear cumulative damage models and life prediction models have been developed to address these deficiencies, but have not been widely accepted.
