(orcid)0000-0002-7665-652X Development of a fatigue life prediction methodology for welded steel semi-trailer components based on a new criterion 2020 Access copy available to the general public Unrestricted This paper presents a procedure developed to predict the fatigue life in components made of steel, based on the mechanical properties of the base material and Thermally Affected Zones (TAZs) owing to welding. The fatigue life cycles of the studied components are obtained based on a certain survival probability provided by a Weibull distribution. This procedure is thought to be applied on semi-trailer components, and therefore it is proposed for the steels that are typically used in its manufacturing. A criterion for the adjustment of the exponent and the stress stroke of the fatigue life curve in welded joints is proposed in which the parameters that define the alternating stress versus the number of cycles to failure (S-N) curve are obtained exclusively from the ratio between the base material yield stress of a given steel and the strength of its Thermally Affected Zone. This procedure is especially useful for steels that do not have a complete characterization of their fatigue parameters. These developments are implemented in a subroutine that can be applied in commercial codes based on Finite Element Method (FEM) to obtain a fatigue life prediction. Finally, a numerical-experimental validation of the developed procedure is carried out by means of a semi-trailer axle bracing support fatigue analysis. info:eu-repo/grantAgreement/ES/MINECO/TRA2012-38826 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.114 2020 MATERIALS SCIENCE, CHARACTERIZATION & TESTING 9 / 32 = 0.281 2020 Q2 T1 ENGINEERING, MECHANICAL 44 / 133 = 0.331 2020 Q2 T2 0.84 2020 Aerospace Engineering 2020 Q1 Automotive Engineering 2020 Q1 Engineering (miscellaneous) 2020 Q1 Safety, Risk, Reliability and Quality 2020 Q1 Materials Science (miscellaneous) 2020 Q1 Mechanical Engineering 2020 Q1 Mechanics of Materials 2020 Q1 Industrial and Manufacturing Engineering 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Castejon, L.
