The paper with the title “Fatigue failure analysis of steel rebars: metallurgical evaluation and numerical simulation” authored by Dr. G. Pantazopoulos, Mr. I. Pressas and Dr. A. Vazdirvanidis from ELKEME S.A. was presented in the poster session of the 8th International Conference on Engineering Failure Analysis (ICEFA 2018),  8-11 July 2018, Budapest, Hungary. The paper presents the investigation results of an early fatigue failure of steel rebar samples, of dimensions of Ø 14 mm, during standard fatigue testing. The rebar tested sample exhibited a crack initiation site close to the root of a surface geometric discontinuity (“nipple”), which is considered as a stress concentration position. Light optical microscopy, microhardness testing, SEM/EDS, macro- and microfractography, as well as numerical simulation using Finite Element Analysis, were employed as the main investigation methods. Dr. George Pantazopoulos was also served as chairman of two sessions “Machine Components” and “Mechanical” which held on 9th and 10th July 2018 respectively.
