    Characterization of the fracture behaviour of a turbine rotor steel by means of the Small Punch test

    The Small Punch Test (SPT) approach has been applied to investigate the properties of a steel grade commonly employed in the construction of high- and mid-pressure turbines.

    Finite element simulations have been carried out employing an elastic-plastic constitutive law and a micro-mechanical damage model for the material, it has been possible to estimate the characteristic load-displacement curve (LDC) of the SPT on the basis of the parameters derived by the simulations on tensile notched specimens (direct analysis). Furthermore, the inverse analysis has been applied to the assessment of the static and fracture properties of the material on the basis of the SPT load-displacement curve. The obtained results show a good agreement between experimental values and numerical predictions.
