Dataset for: "Fatigue assessment of welded joints subjected to multiaxial loading conditions through the Effective Critical Plane approach"

Dataset description This dataset accompanies the article “Fatigue assessment of welded joints subjected to multiaxial loading conditions through the Effective Critical Plane approach.” It contains the experimental fatigue-life data and the corresponding fatigue-life predictions presented in the article. Each .txt file represents a specific combination of fatigue-assessment method, specimen geometry, loading condition, post-weld or heat-treatment condition, and load ratio. File-naming convention For uniaxial loading conditions, filenames generally follow the structure: _ _ _ _R_ .txt For multiaxial loading conditions, the filename also includes the nominal stress ratio (\lambda) and the load phase: _ _Multi_ _Ph_ _ _R_ .txt where: METHOD_NAME identifies the fatigue-assessment method or equivalent parameter; GEOMETRY_TYPE identifies the specimen or welded-joint geometry; LOAD_TYPE identifies the applied loading condition, such as axial loading, bending, torsion, or multiaxial loading; LAMBDA is the nominal shear-to-normal stress ratio, defined as(\lambda=\tau_{\mathrm{nom}}/\sigma_{\mathrm{nom}}); Ph identifies the load phase angle for multiaxial loading; POST_HEAT_TREATMENT identifies the weld, material, or heat-treatment condition; R is the applied load ratio. Decimal values in filenames are written using underscores instead of decimal points. For example, 0_44 corresponds to 0.44 and 1_625 corresponds to 1.625. As an example, the filename FS_1_A_Multi_0_44_Ph_90_AW_R_-1.txt identifies results obtained using method FS_1 for geometry A, under multiaxial loading with (\lambda=0.44), a load phase of 90°, the AW condition, and a load ratio of (R=-1). File contents The files are plain-text, tab-delimited files without a header row. Each row corresponds to one experimental fatigue test and contains three columns: Experimental number of cycles to failure; Equivalent fatigue parameter calculated using the method identified in the filename; Predicted number of cycles to failure. The definitions, units, material conditions, specimen geometries, and calculation procedures associated with the equivalent parameters are provided in the reference article.
