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, and is used to obtain the mechanical properties of the foil. This work describes a method to determine the yield stress and ultimate tensile strength of aluminum alloys, using SPT and an "Inverse procedure" which uses advanced numerical methods (finite element model (FE), artificial Neural network (NN)).
The SPT method was examined using experiments, a verified and validated FE, and comparison to tensile test results. Several aluminum alloys were tested.
The developed FE and NN model can adequately reproduce the experimental results and is suitable for understanding the stresses/strain distribution during SPT of aluminum miniature samples. The applicability of SPT and its ability to obtain the mechanical properties of different aluminum alloys, using the "Inverse procedure" will be discussed.
