Abstract
The paper present the installation and the methodology for numerical analysis, usingfinite elements method that has been used for the breaking test of the aluminum pipes andalso the general characteristics of the experimental results. The tested pipes have thesame diameter D = 18 mm, but different wall-thickness: 2 mm for the civil constructionpipes and 0.9 mm for the hydro melioration pipes. The time - pressure diagram ispresented. The value of the breaking pressure for each tested pipe is determined, firstfrom the theoretical approach and second, from the experiment. The solutions based onthe classic beam structural theory and the detailed finite element analysis results havebeen confronted.
