On the equivalence of mini-flat and cylindrical tensile geometries to extract hardening law and ductility of Eurofer97

Properties extracted from uniaxial tension provide fundamental information about the strength and ductility as the first input for the structural analysis, conventionally performed by means of finite element computations. In recent years, there has been a growing interest in evaluating the mechanical properties of materials using small specimens, especially in the nuclear industry due to limited volumes available in test facilities and limitations on wastes. The application of miniaturized flat sample geometries offers a number of advantages in terms of exposure to irradiation or extraction of samples using modern tools. However, the applicability of flat geometries should be validated.
