A Study on the Prediction of the Fatigue Life of a Lug through the Finite Element Analysis

FEA를 이용한 Lug의 피로 수명 평가에 관한 연구

The purpose of this study is to predict the life of a Lug under the real service load history. The techniques of predicting a fatigue life under load spectrum are discussed and some are developed. The stress is calculated by multiplying the stress under unit force with the Finite Element Analysis. The cycles are counted by the Rainflow counting method and then the mean stress effect is considered by the suggested conversion function. The Manson's Double Linear Damage Rule is used as the cummulative damage method.
