Complete Data Record The advanced data collection system automatically saves all relevant signals, active calibrations, and system settings. The powder accessory for the DMA is used with the dual cantilever clamp to observe transition temperatures of loose powdered materials by DMA, combining the enhanced sensitivity of mechanical analysis with the simple sample preparation of powder characterization techniques.

Go beyond conventional DMA testing and program experiments that mimic complex real-world conditions through an unlimited combination of 23 available steps. A unique low-friction, roller bearing supported design available on the 20 mm and 50 mm clamps improves modulus accuracy and reproducibility by accommodating and accounting for twist or curvature in the test specimen. The continuous travel of the DMA makes sample loading in tension q8000 convenient.
Two equal-size pieces of the same material are sheared between a fixed and moving plate for the measurement of shear modulus, G.

Accurate sample temperature is obtained by a thermocouple placed within the fluid reservoir and close to the sample Inert stainless steel construction and a seal-free design dmw compatibility with a wide range of fluids Temperature control provided xma the Standard Furnace without additional circulators or environmental systems. Auto-Ranging Because the modulus of a material can change by several orders of magnitude in a narrow range of time or temperature, the selection of programming parameters can make or break an experiment.
Onset and endset analysis Signal maximum and minimum Signal change Modulus crossover Curve values at specific X or Y points 1 st and 2 nd derivatives Area under the curve Peak height Peak integration, and running integral Mathematical fitting: The motor is constructed of high-performance lightweight composites that maximize axial and torsional stiffness while minimizing system inertia. Non-contact, low mass motor delivers continuous forces from 0.
Data Analysis A comprehensive set of dms tools are available for real-time data analysis, even during experiments. Powder Clamp The transition temperatures of loose powders can be difficult to measure by mechanical techniques.
The result is the most stable platform for mechanical characterization of materials even under extreme conditions. A newly designed film tension clamp simplifies the clamping mechanism to improve ease-of-use, clamping uniformity, and effectively prevents sample slippage.

Unlike competitive motor designs that provide either high force or high resolution, or require separate inferior motors for linear travel, the DMA achieves a continuous range of linear travel and high-resolution force measurement. Faster electronics, sma new digital signal processor DSP controls, and d,a enhanced drive system allow for an all-new type of strain control in the DMA The DMA is the only commercial DMA instrument to feature a temperature-controlled force and displacement transducer, providing unparalleled measurement stability and accuracy.
Gain actionable insights into your material behavior through a powerful and versatile set of features seamlessly integrated into TRIOS. The rectangular shape of the drive shaft completely eliminates off-axis motion.
The critical drive components of the DMA are mounted within a high-stiffness aluminum casting that is rigidly mounted to an FEA-optimized instrument frame. If the deformation chosen is too large there could be excessive sample creep.

View brochure Contact Us. The penetration kit is designed for higher stiffness materials and local measurements through the use of smaller probes: The new DMA Express interface is designed specifically for new users and those with simple, well-defined experimental requirements it presents test setup details in easy-to-choose, self-contained forms.
The user is presented with all necessary testing parameters in a self-contained window, populated with sensible default starting parameters. The sample chamber mounts directly to the DMA. Each clamp is individually optimized for accuracy and ease-of-use. The advanced data collection system automatically saves all relevant signals, active calibrations, and system settings.
Waveforms for each data point may be displayed as Lissajous plots and provide a visual representation of the stress-strain relationship. Parallel plate compression measurements are most suitable for low to moderate modulus materials such as foams and elastomers. Dual cantilever is especially ideal for measuring the cure of supported thermosets. Because the modulus of a material can change by several orders of magnitude in a narrow range of time or temperature, the selection of programming parameters can make or break an experiment.
The transition temperatures of loose powders can be difficult to measure by mechanical techniques. The slide is guided by eight porous carbon air bearings. The DMA offers your choice of two dedicated environmental systems: Cantilever clamped bending is a good general-purpose mode for evaluating thermoplastics and highly damped materials e.
