    Abstract

    A review of the application of fractography to fatigue studies is presented that covers fatigue fracture appearance, the occurrence of striations, and qualitative and quantitative aspects of the fracture surface microdetails. Recent experimental results in three areas are also discussed: (1) the effect of prior loading history on subsequent crack propagation, (2) the smallest observable crack growth increments, and (3) the effect of environment on fatigue crack growth.
