R. Citarella et alii, Frattura ed Integrità Strutturale, 34 (2015) 514-523; DOI: 10.3221/IGF-ESIS.34.57 522 accurately plan the level of interference values to be adopted when coupling hubs and axles. There are some advantages when using DBEM rather than FEM for this kind of non-linear fracture problems: simplified modelling of the cracked area and accurate crack growth simulation especially when tackling contact loadings. Further developments of this work will be devoted to resolution of the same problem by FEM in order to benchmark the two methodologies with reference to preprocessing effort, accuracy and runtimes, even if some results have already been anticipated in this paper showing a satisfactory level or correlation.
