Dynamic Mechanical Analysis
the key to control the thermo-mechanical
performances of materials
Dynamic Mechanical Analysis consists of applying a
vibration of known amplitude and frequency (off
resonance frequency) to a material specimen.
Measurements of the applied displacement and the
resulting force lead to the precise determination of
viscoelastic properties, the Young’s modulus (E*), or
shear modulus (G*), depending on the deformation
mode.
Dynamic Mechanical Analysis (DMA) is a major
characterization technique used to control mechanical
performances and the temperature behavior of materials.
Possible applications are constantly being developed.

Because requirements in research or industrial testing have broadened considerably 01dB-Metravib has
developed products that can measure glass transition temperatures, follow-up of transformation processes,
robotized characterization of viscoelastic properties of specimens, etc.
Based on a great capacity for innovation and recognized expertise in structure calculation, vibration, and
physical measurements of materials, 01dB-Metravib has developed a unique range of instruments meeting
multiple requirements along two major axes:
❚ scientific research:
to understand the relationships between the material’s molecular structure and its mechanical
properties,
❚ industry:
to control the key performances of manufactured products in their conditions of use and ensure
their manufacturing quality and lifetime

DMA 50 : accurate, versatile & cost-effective
Versatile and flexible
Flexible operating modes allow for instant repeating of
routine DMA and TMA tests, as well as for the definition
of specific tests combining multiple parameter settings.
Depending on the test configuration, the position of the
mechanical frame can be easily reversed.
For tests requiring the specimen to be immersed in
liquid, this function is particularly effective, since it
allows use of all the available specimen-holders, regardless
of the stress mode and does not require the
purchase of expensive accessories.
DMA 50 is a desktop DMA offering a high force range
and outstanding flexibility from glass transition determination
to immersed tests, which makes it a thermomechanical
testing platform.

Planar shear
Unique mechanical features and technological control
The very high rigidity of mechanical frames is one of the key points of the
DMA+ performances.
The technologies used to generate the excitation signal, measure the displacement
and force transferred to the specimen have been specifically developed
by 01dB-Metravib engineers, experts in vibration mechanics, to provide the
DMA+ range with the optimum performances required for a fine analysis of
viscoelastic material properties.
Shear for liquids
Shear for pasty materials
3-point bending Single/dual cantilever
This allows DMA+ to carry out high-precision measurements of complex
moduli and of Tan delta.

Characterization of non-linear properties
of elastomers
Applications of analyzers
Regardless of their formulation, elastomers follow complex behavior laws under static and
dynamic stress.
Due to an accurate control of the deformation ratio applied to a specimen and to an
important excitation force, DMA+ 450 allows for the analysis over particularly broad ranges
of deformation ratios: from 0.1% to 300%.
Multiple parameter settings are available in Dynatest and can be used to simulate complex
stress conditions very precisely and make DMA+ must-have tools for the dimensioning
and optimization of the mechanical behavior of elastomer parts.
Melting : 128°C
Tg : 82°C
Fatigue test
Fatigue tests can be performed with the DMA+ range of instruments, using the Multidyn
software.
The test opposite shows the important decrease of the material’s modulus after 100000
cycles and the evolution of its response through Lissajou curves.
The test can be performed using a controlled waveform, which allows to reproduce specific
test conditions that are representative of the material’s final use.
Measurement of glass transition and melting
DMA is recognized as the most accurate technique to determine the glass transition
temperature (Tg).
The Tg measurement precision of MetraviB DMA results from many technical innovations
and specificities: auto-calibration of the loss angle measurement, quality of the thermal
control, control of test dynamic conditions...
By convention, the analysis is commonly performed at 1 Hz. In the example opposite, a PET
specimen was analyzed between tension/compression clamps. The test was then carried
out at high temperature, which also allowed to determine the melting temperature. It has
evidenced the unique capacity of DMA+ to characterize huge variations in mechanical
properties: during the test, the module can vary by a 50000 factor!
Tg : 48°C
Measurement of secondary transitions
The determination of these very small-amplitude phenomena (β and γ transitions) on the
Tan delta curve yields information on the impact resistance performances of polymers.
The broad stiffness analysis range and the measurement precision of MetraviB analyzers
allow to perform this type of analysis in very diverse stress modes and geometries
depending on the available materials.
Characterization of materials ageing
The comparative analysis of a new composite material and of the same material subjected
to thermomechanical ageing has showed markedly different mechanical properties: glass
transition temperature, damping and elastic modulus.
In the example opposite, material ageing led to a 4-fold decrease of the elastic modulus and
to a 40°C increase of the glass transition temperature, with a drastic loss of the damping
factor (from 0.32 to 0.17).
β : -18°C
New material
Aged material
Immersion Test
Immersion test
The impact of water absorption on the mechanical properties of a polymer can be characterized
by performing the test on a polymer specimen immersed in water.
DMA 50 makes this test very simple. One just need to put the mechanical frame upside
down and once the specimen is set into place, to immerse it into a bath. All specimen
holders of DMA 50 can be used for this type of test.
In the example opposite, one can note the instant fall of the modulus upon immersion, which
continues until the specimen breaks up.
Tg (10Hz) : 155,8°C
Tg (0,1Hz) : 144,6°C
Frequency effect
The excitation frequency can have a significant influence on the modulus and loss factor a
polymer material. Also, the glass transition can change significantly depending on the
excitation frequency.
Characterizing the frequency dependence of the material behavior will then be all the more
important as the material is dynamically stressed in its final use, in particular if it is used for
a damping function in a vibratory environment.
In the example opposite, an epoxy resin exhibits a Tg increase of 15°C for an excitation
varying from 0.1 Hz to 10 Hz.
Prediction of long-term creep
Performing a few-minute creep test on different consecutive temperature plateaus has
allowed, based on Dynatest TTS (Time Temperature Superposition) calculation, to predict
the material’s creep over several months or years.
The creep test can be performed in stress modes, usually 3-point bending modes for highmodulus
materials, but also, based on DMA+ performances (very rigid frame and high
excitation force) using tension clamping jaws on specimens with significant geometry, in
regards to material's structure.
Gelification
1 year 10 years
Fluidizing
Optimization of a transformation process
The polymer cross-linking reaction is characterized by the transition from pasty state to
solid state, via a fluidizing phase, under the competing effects of the temperature and of the
chemical reaction. The great rigidity of the DMA+ 150 frame and the auto-control mode of
Dynatest allow for the constant monitoring of the shear modulus during a single test and
for the determination of process-characteristic times: minimum viscosity, gel time, etc.
Depending on the nature of the material (prepreg, resin, etc.), different specimen holders
can be used to perform this type of test. In the example presented here, a thermosetting
resin was analyzed in shear mode. Characteristic points, along with important variations of
the modulus (10-million factor!) during the test, were collected.
