Random Initial Defects and Fatigue Life Prediction

  • V. V. Bolotin
Part of the International Centre for Mechanical Sciences book series (CISM, volume 334)


A systematic study is presented of influence of initial and newborn defects on the fatigue lifetime and reliability measures of structural components. A survey of models of fatigue crack initiation based on various accumulation concepts is given. The influence of the random material microstructure and specimen-tospecimen variability and mechanical properties on the fatigue crack growth and fatigue life is studied with the use of numerical simulation techniques. Methods of assessment of structural risk in the presence of sets of cracks and crack like defect are discussed with a special emphasis on the extrapolation of results in the area of small probabilities.
