Intralaboratory comparison for the anisotropy test of sheet metals

Abstract

The plastic strain ratio is an important parameter for the evaluation of the anisotropy of sheet metals in deep-drawing processes. This paper presents the results of an intralaboratory comparison for the anisotropy test, using normalized error as statistic method of analysis. The study was carried out through the comparison of the results obtained from different operators for the same sheet metal. The results of the study are considered satisfactory.
