Dynamic thermomechanometry (or dynamic mechanical analysis, DMA) A technique in which the dynamic modulus and/or damping of a substance under oscillatory load is measured as a function of temperature whilst the substance is subjected to a controlled temperature program. 

Measure and of the sample using either tosional braid analysis (TBA) or dynamic thermomechanometry (DMA). 

Thermomechanical analysis (TMA) is a technique in which the deformation of a substance under a nonoscilla-tory load is measured as a function of temperature while the substance is subjected to a controlled temperature program. It is used extensively in polymer studies. The mode, as determined by the type of stress applied (compression, tension, flexture, or torsion), should always be noted. As already stated, dynamic mechanical analysis is a technique in which the viscoleastic response of a sample under an oscillatory stress is studied while the substance is subjected to a temperature regime. Torsional braid analysis is a particular case of dynamic thermomechanometry where the material is supported.
