Urządzenie do prób skręcania ze statycznym rozciąganiem

In the paper an apparatus for static and dynamic torsion tests with static tension of a thin-walled specimen is described. With the use of finite elment method the states of stresses in the specimen have been analysed. The paper contains remarks on elastic-plastic stability of the specimen during torsion tests with tension. At the end of the paper some experimental results of strain-induced austenite transformation in a stainless steel are presented.
