Smart Material Testing ears of an 40 y premiumh More t R&D for is analys ce in anical erien exp mech namic ality dy qu Successful introduction of materials and products onto the market is always preceded by a great deal of testing to determine suitability in day-to-day applications. Temperature, time, frequency, load level and other parameters change the visco-elastic properties of polymers and composites. How are your products influenced by different temperatures or moistures? How do the material properties depend on mechanical loading or different frequencies? What is the lifetime of the...

Dynamic Mechanical Analysis The Dynamic Mechanical Thermal Analyzer applies forced periodic loads to the sample and analyzes the phase shift between this primary excitation and the material’s response. The response of an ideal elastic system (e.g., spring) on a sinusoidal load at a given frequency is of the same frequency and exactly in phase with the excitation. The situation changes in a real system: A phase shift (δ > 0°) between the primary excitation and response of the same frequency occurs in the case of linear visco-elastic materials (e.g., polymers); see figure 1. Elastic and...

DMA GABO EPLEXOR® Series MODULAR DESIGN The DMA GABO EPLEXOR® high-force systems allow for a variety of upgrades – addressing tomorrow’s tasks today!

– ALL SET FOR THE FUTURE Set for the Future The DMA GABO EPLEXOR® series allows for easy upgrading of the system with a variety of force, sensors and strain extension as well as furnaces. For non-stop operation, a fully automatic sample changer is available. The different DMA GABO EPLEXOR® versions are operated without a hydraulic pump system – thus providing energy-efficient operation. Results-Oriented Tailoring of Force Range This one-of-a-kind DMA system offers the ability to install different force sensors to meet individual users’ needs, with a maximum force range from ± 10 N to ± 2500...

First-Rate Performance via Stiff Frame Unique by Virtue of Real-Time Operation and Digital Signal Generator Perfect Loading Flexibility Thanks to Two Independent Drives The DMA system allows for real-time operation. The quasi-continuous frequency range with high data acquisition rate allows for operation between 0.001 Hz and 100 Hz. Frequency sweeps with high detection sensitivity are suitable for detecting even weak transitions and can be taken for master curve generation. The frequency range can be extended (0.0001 Hz; 200 Hz). Static and dynamic force can be actuated independently. The...

and Real-Time Operation High Stiffness for Reliable Testing High-Safety Fatigue and Tensile Tests Linear and Nonlinear Mechanical Characteristics Under Application Conditions The DMA GABO EPLEXOR® series up to ± 500 N uses a very stiff frame which allows for direct compression measure-ments on solid samples below glass transition from -160°C upward in strain-controlled measurements. The low compli-ance enables investigations on stiff samples such as metals, ceramics and composites. Fatigue or tensile tests at high force levels are often destructive experiments. The shock absorption property...

A Variety of Sample Holders for Handling the Tasks of Today and Tomorrow Any investigations, characterizations and quality control tests conducted on a material should be in line with its application. The results obtained via measurements which closely parallel real applications allow for more accurate appraisals of a material’s true performance. A variety of sample holders in standard geometries (e.g., bending, tension) are available, as well as in dedicated userdefined geometries. Immersion systems are also offered. THE PERFECT SAMPLE HOLDER FOR ANY APPLICATION Film tension Fiber cord...

More Investigative Power through IMMERSION & HUMIDITY – SIMULATION OF ENVIRONMENTAL INFLUENCES Immersion for Testing Swelling Behavior and Other Effects The immersion bath allows for measurements in a liquid such as water or oil in combination with sample holders such as those for 3-point bending tests (picture on the right) or tension tests (picture on the left), in cases where evaporation and decomposition temperature of the solvent or liquid are not an issue. The plot below shows results of room temperature measurements on rubber carried out at a prestrain of 20% and a frequency of 10...

Add-Ons Environmental conditions may cause water uptake and therefore play a decisive role in manufacturing processes and the storage of materials. The DMA GABO EPLEXOR® in combination with the HYGROMATOR® humidity generator is able to create a humid environment inside the test chamber to reveal the influences of environmental humidity on mechanical properties. HYGROMATOR® – The World's First Climate Chamber for DMA The HYGROMATOR® can adjust humidity from 5% rH to 95% rH in the temperature range between 5°C and 95°C. Measurements can be performed under stepwise humidity variation....

DIPLEXOR® – SIMULTANEOUS DMA AND DEA For the simultaneous determination of dielectric and mechanical properties, special sample holders and a dielectric controller are available for the DMA GABO EPLEXOR® systems. Dielectric analysis (DEA) explores the structure of a material by applying a sinusoidal voltage to two electrodes at a defined frequency. In combined DMA-DEA measurements, the frequency ranges from 10-2 Hz up to 107 Hz. The electrodes hold a solid dielectric specimen between planar capacitor plates. The tests are carried out in compression mode. An alternating current results...
