Abstract: Using the local stress and strain method, this paper presents an engineering approach to predict the fatigue life for coldworked fastener holes. The approach is based on the fatigue experiment, fracture analysis and residual stress computed by elasto-plastic finite element method. The fatigue life predicted by the approach is well agreed with the experiment. The approach is convenient and spends less computer time.
