Abstract

It is a common practice to use automated software tools to identify material properties values in dataset recorded during the tensile tests. Our work is a comparative study how different numerical algorithms affect resulting material properties values. We tested four different algorithms on fifteen dataset while datasets covered all the most common metal force-deformation characteristics. Two algorithms can be considered as validated according to the standard while two others need some minor modifications. We expect that after these modifications also the two algorithms will meet evaluation requirements. Effect of using different validated algorithms is relatively small but still it needs to be considered as a source of uncertainties in entire physical test and evaluation chain.
