The Small Punch Test (SPT) is a mechanical testing method in which a foil is bended to failure using a ball punch, while the force-displacement curve is recorded. This curve is used to obtain the mechanical properties of the tested material. This method is often used to obtain the properties of irradiated materials that are available only as miniature samples. In the current study, disc samples with a diameter of 3mm and thickness of up to 260Ám were tested. Standard aluminum alloys were used to investigate the effects of various test parameters on the obtained results. A verified and validated numerical finite element model (FEM) of the testing device was developed. The SPT and FEM were used to investigate the mechanical properties and the unique microstructure of additive manufactured (AM) aluminum. The applicability of SPT and its ability to obtain the mechanical properties for AM materials will be discussed.
