The University of Natural Resources and Life Sciences in Vienna, Austria Relies on Testing Technology from ZwickRoell

The Institute of Physics and Materials Science of the University of Natural Resources and Life Sciences in Vienna (BOKU) focuses on the study of the micro- and nanostructure of materials and their influence on the physical and mechanical properties. The demands on a testing machine are diverse. A number of different materials are tested in a range of applications, from basic research to customer-specific development projects. For this reason the University chose a highly flexible and reliable testing machine from ZwickRoell.
In addition to basic research, the Institute of Physics and Materials Science conducts intensive contract research together with industrial companies. Materials are characterized under various loads, and at elevated and low temperatures. The testing machine also finds application in groundbreaking tests on the time-dependent material properties of composite mortar systems as part of the fundamental research conducted by the Christian Doppler Laboratory for Life-Cycle Robustness in Fastening Technology, which is also located at the BOKU and with which the Institute for Physics and Materials Science has intensive scientific collaboration. BOKU uses an AllroundLine materials testing machine with Fmax 10 kN and an integrated temperature chamber (- 80 °C to + 250 °C) for exact simulation of different ambient temperature scenarios. Reliable test results are paramount to this machine. In addition to the low vibration design and optimal use of extensometers, it is important to mention its precise temperature conditioning. The sophisticated air-feed system ensures extremely uniform temperature distribution, and precision control guarantees stable temperatures with no overshooting. With the use of preconfigured control parameters the temperature is attained quickly and precisely. In connection with the ZwickRoell System Configuration Builder, specimen-specific control parameters can easily be loaded with the test program. The optional close-proximity temperature sensor enables temperature control at the critical sensor location, for optimum test results. Among others, the following tests are performed with the testing machine. 1. Flexure tests in accordance to and based on DIN EN ISO 178 2. Fracture tests to ASTM D 5528 3. Shear tests to ASTM D5379 4. Fracture toughness tests to ASTM D 5045 Due to the modular structure of the testing system, additional specimen grips and test fixtures for other types of tests can be integrated at any time.
