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