4. Summary The topic of this paper was motivated by the paradigm shift in SIC methodology that requires more and improved quality data from materials testing. For tensile testing, a finely tuned measurement system and an appropriate data acquisition system were developed. By adopting the DT concept, Finite Element models have been constructed to examine the influence of varying initial specimen geometries on the outcomes of the measurements. It can be concluded that the simulations performed on small-size specimens –which were also investigated by experiments– can be used to assess manufacturing-induced geometric imperfections. The results are of considerable importance for future investigations, as they allow identification of uncertainties due to geometrical imperfections of the specimens and those due to the inhomogeneous distribution of material properties.
