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.
