The new DMA+ series instruments are dynamic testing machines based on a brand new concept and dedicated to analysis of viscoelastic properties (DMA) and to fatigue tests of advanced materials and industrial components, as well as to the follow up of crack growth.

The DMA+ new high-rigidity one-piece test frame has been designed to offer optimal stiffness and frequency analysis ranges, along with first-class ergonomics.



ASSETS

The new DMA+ series instruments rely on the most advanced technology to achieve high-precision analysis of mechanical properties, as well as ultimate flexibility; among their many assets:

Frequency: from 0.00001 Hz to 1000 Hz
Displacement (p-p): 12 mm
Thermal chamber: from -150°C to +500°C
High-rigidity one-piece mechanical frame
High precision measurement
DMA, TMA, creep, stress relaxation, fatigue, crack growth, calorimetry modes on a single instrument
Tension/compression/bending/shear
Analysis of specimens with material-representative size
Advanced algorithm for precise test control
Broad selection of specimen holders for multiple geometries and dimensions
Optical specimen observation system (option)
Easily upgradeable to meet specific analytical requirements
Atmosphere control (option)
Humidity control (option)
Optimised working ergonomics
Reduced maintenance
Reduced footprint

APPLICATIONS

The DMA+ series instruments offer a broad range of applications, among which:

DMA and TMA testing
Precise measurement of viscoelastic properties
Determination of glass and secondary transitions
Static and quasi static testing: creep, stress relaxation, tension, compression…
Fatigue testing on material and industrial component specimens (with controlled waveform)
Crack growth testing
Analysis of solid, pasty and liquid materials: elastomers, plastics, composites, biomaterials, etc.
Particularly well suited to polymer and composite characterization (polymerised materials, follow-up of polymerisation process, simultaneous DMA/calorimetry, fatigue)
Particularly well suited to elastomer testing and characterization (Mullins effect, Payne effect, frequency sweep, self heating, crack growth testing, etc.)
Materials humidity dependence analysis
Comparison and classification of complex materials for design engineering
