Thermo dilatometry

Thermomechanical analysis (TMA) is a technique that measures the deformation of a substance under non-oscillatory load or strain as a function of temperature or time. Thermo-dilatometry (see Section 2.2.4) is a technique that measures dimensional changes of a sample as a function of temperature or time. Both of these techniques can be applied using the same apparatus. The sample is heated or cooled at a certain rate, or is maintained isothermally at a fixed temperature. 

Other thermal analysis techniques such as dilatometry in Sect. 4.1 or thermo-mechanical analysis in Sect. 4.5 can also be used to study the time dependence of T. Especially suited for measurement of the frequency response are dynamic mechanic analyses in Sects. 4.5.4 and 4.5.5, and dielectric thermal analyses in Sect. 4.5.6. Although the different techniques respond to different external excitations, the obtained relaxation times are similar, as shown in Fig. 6.117. Over wider temperature...
