Abstract The paper presents the effect of stress concentration on duplex steel S32750 (according to UNS standards or W.Nr. 1.4410 according to EN standards) behaviour under impact loading. This analysis is based on the results obtained by experimental testing, with particular focus on the influence of crack-like defects on material behaviour under impact load. Keywords: duplex steel S32750, impact testing, fatigue crack growth, crack sensitivity factor |
