  • Thermo mechanical analysis (TMA) easily and rapidly measures sample displacement (growth, shrinkage, movement, etc.) as a function of temperature, time, and applied force.

Applications

  • Tension studies of the stress/strain properties of films and fibres

  • Determination of softening behaviour

  • Glass transition temperatures and secondary transitions

  • Phase change determination

  • Determination of mechanical behaviour under applied force

  • Determination of expansion coefficient (dilatometry)

  • Sintering behaviour

  • Volumetric expansion

  • E modulus

  • Slipping and friction resistance

Traditionally, TMA is used to characterize linear expansion, glass transitions, and softening points of materials by applying a constant force to a specimen while varying temperature. For expansion measurements, a probe rests on a sample on a stage with minimal downward pressure. Other constant force experiments include measurement of penetration, bending, tension, shrinkage, swelling, and creep (sample motion measured as a function of time under an applied load).

In Dynamic TMA (DTMA), a known sinusoidal stress and linear temperature ramp are  applied to the sample, and the resulting sinusoidal strain is measured.
