The diploma thesis is focused on the analysis of the behavior of the thin-walled tubular test specimen during the technological test of the liquid draining of the tubes. The test specimen ‘in the form a tube was made of austenitic stainless steel 17 240 (1.4301, X5CrNi18-10). During the experiment, the radial expanding tool was quasi-statically charged by the internal fluid pressure. In the introductory part, the thesis focuses on the stress-strain description of the method of tube bulging and possible ways of detecting the strain of material during forming. The experimental part is primarily focused on the analysis of the test sample that was obtained from the experiment. Theoretical approaches were used to analyze the real test sample to detect strain and stress in material, numerical simulation of the bulge process and 3D ATOS scanning device, which helped clarify behavior tube during bulging process. At the end of the thesis is proposed possible design of the tool. This modification should contribute in the future to the full functionality of the radial expanding tool, or the bulging of the tube by liquid.
