ABSTRACT
Scant and incomplete experimental evidence, especially on full-size structural components, has inhibited a widely acceptable and quantitative statement on the effect of R-ratio variations on fatigue strength. Before the background of accumulating experimental data with the aluminium beam fatigue testing program at TUM and new comprehensive data on small specimens made available to eva - luation lately, an attempt has been undertaken to account for such effects in the European Recommendations for fatigue design of aluminium structures.
