We investigate the effect of a galvanizing coating on the fatigue strength of S355 structural steel. Although some results on fatigue tests of unnotched specimens are available, those on notched components are scarce.

Abstract
We investigate the effect of a galvanizing coating on the fatigue strength of S355 structural steel. Although some results on fatigue tests of unnotched specimens are available, those on notched components are scarce. A comparison is carried out between hot-dip galvanized specimens weakened by a central hole and untreated specimens of the same geometry for two nominal load ratios R = 0 and R = −1. In total, over 60 new experimental data are summarized and analyzed in the present contribution.File in questo prodotto:
