AB This work aimed to study the fatigue behaviour of S355 low carbon steel under uniaxial and biaxial loadingconditions and to measure the overload effects under both types of loads. The analysis is performed with a localstrain approach and with damage tolerance approach. Local strain based investigation was based on Fatemi Socie critical plane model. This allows the life reduction caused by growing the crack from a stress raiser to bequantified. The fatigue life reduction caused by applying simultaneously torsional and tension loads was alsoevaluated with Fatemi-Socie model. In addition, the crack opening displacement (COD) and the effective stressintensity factor (SIF) were evaluated experimentally via full-field technique of digital image correlation (DIC).Both COD and SIF have been useful to understand the transient effects caused by a 40% overload under the twotypes of load. In addition, COD measurements allowed the offset compliance method for evaluating the openingload to be applied on a cylindrical specimen subjected to tension load. SIF estimation was also useful to quantifythe mode mixity (I + II) developed during the experiment under the two types of load.
