This accessory for WP 310 makes it possible to carry out tensile experiments on round specimens. The tensile strength is determined as an important characteristic of a material. Additionally, the fracture strain can be determined as a measure for the material’s toughness. The specimens meet the requirements of DIN 50125, B10x50 and have threaded ends.
The accessory contains two clamping heads with threads for holding the round specimens. Both clamping heads aresecured to the crossbars of WP 310.
In the tensile test, a uniaxial state of stress is produced in a standardised specimen. This state of stress is produced by an external load on the specimen in the longitudinal direction via a tensile force. Then a uniform normal stress distribution prevails in the test cross-section of the specimen. In order to determine the strength of the material, the load on the specimen is slowly and steadily increased, until the specimen breaks.
A set of round specimens made of steel is included to carry out experiments.
