摘要：

The variable-amplitude loading encountered in service often includes compressive excursions. It has been a common practice to ignore these excursions for fatigue crack growth analyses. Recently, experimental data on both smooth bars and cracked specimens with intermittent negative R ratio loadings have indicated that the effects of compressive excursions are not negligible.
