ALMAGUER-ZALDIVAR, Pavel-Michel  e  ESTRADA-CINGUALBRES, Roberto-Andrés. Evaluation of the fatigue behaviour of a butt welded joint of AISI 1015 steel. Ingeniería Mecánica [online]. 2015, vol.18, n.1, pp. 31-41. ISSN 1815-5944.

Welded joints are an important component in structures, by this reason is necessary to know the behaviour of these elements under cyclic loads. The objective of this work is to obtain the S-N curve of the butt welded joint of AISI 1015 steel and electrode E6013 as the contribution material. Fatigue test was realized within the ASTM standard in the MTS810 testing machine. Rectangular cross section specimens was used. Cyclic loads was asymmetric tensile and the asymmetry ratio used was 0,1. In this study was obtained the fatigue limit equal to 178 MPa, at the cut point of 2 039 093 cycles.

Palavras-chave : welded joint; fatigue; S-N curve; AISI 1015 steel; electrode E6013.
