[en] Automatic translation: For the investigation of the mechanical behaviour of metall. materials under long-term creep loading, the IRW has 20 single specimen furnaces at its disposal. The load as a significant influencing factor during the test should generate a largely uniaxial stress state in the specimen. The current design of the testing machine often leads to high bending stress components, which depend on the size and direction of the specimen installation. In order to be able to influence the undesirable stresses, the rigid tie rod holder with shoulder head was redesigned as an articulated bearing. Furthermore, a digital displacement recording system was installed with a tap on the load lever of the machine in order to be able to track the creep of the specimen on the lever movement.
