Abstract Scope |
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. |
