The Tensile Test of Tubes
Janda, Luděk ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
The present thesis deals with the tensile test of tube samples and verifies the possibilities of obtaining the corresponding material characteristics. In this work, a total of 3 types of tube samples made according to ČSN EN 10002-1were investigated. For the experiments, longitudinally welded tubes made of 17 240 steel were selected. The used tube was marked as a thin-walled one. Tensile tests were performed on 22 the samples, namely 8 samples on samples having a form of a cut-off of a full cross section tube, 10 samples a strip of segment cross section and a 4 samples transverse cut-out of tube. The goal of thesis was to validate options of acquiring material characteristics, value of deformation hardening exponent ,,n,, and material characteristic ,,C,, of tube samples. Further examination was aimed at designating which shape of sample tubes used for tension test is most suitable. And behaviour of individual samples was examined with tensile load applied. Tension tests were conducted on hydraulic test machine ZD40.
