This article analyzes the behaviour of a tube sample during the flaring process. The evaluation is carried out using non-contact 3D optical measuring system ARAMIS, which is ranked among the most modern measuring methods of deformations nowadays. The methodology of experiment including the measurement of the required values using GOM Correlate is described in this paper. The stress-strain path of an observed point was created based on the measurement values. The curves of the stress distribution and change of the wall thickness depending on the height of formed tube end were drawn too.
