DMA Deformation Modes & Clamping Assemblies - METTLER TOLEDO

Deformation Mode

Swiss Quality

In a DMA, you can deform your sample in different ways. Each deformation mode has its advantages.

The DMA/SDTA861e has 4 different deformation modes:

  • Shear
  • Bending (3-point bending, dual cantilever and single cantilever)
  • Tension
  • Compression

 

 

Small clamping assembly

Large clamping assembly

Bending

 

3-point bending clamp
Dual cantilever clamp
Single cantilever clamp

Tension

Small tension clamp (9 mm)

5.5 mm tension clamp
10.5 mm tension clamp
19.5 mm tension clamp

Shear

Small shear clamp
Small shear clamp (liquid)
Small shear clamp (without texture)

 

Compression

 

Large compression clamp

 

Shear clamps

 

The great advantage of the shear mode is that everything from viscous to hard samples can be measured.

It is suitable for elastomers, thermoplastics and thermosets.

Small and large tension clamp

This mode is most suitable for films, fibers and thin bars. The advantage is that the clamping of the sample has practically no influence on the deformation of the sample.

Bending beam with 3-point bending and cantilever clamps

The 3-point bending mode is particularly suitable for hard samples such as reinforced thermosets, composites, metals and alloys.

This mode is especially suitable for samples that would otherwise bend excessively under static stress.
Examples of this are thermoplastics and thermosets.

This mode is suitable for samples that expand or shrink strongly along their length during the measurement.
This is in particular the case with thermoplastic samples.

Compression clamp

This type of measurement is suitable for soft materials (pasty materials, elastomers and foams).
