TABLE OF CONTENTS As described in Chapter 1, several Special Techniques have been developed from the Primary Technique known as Thermomechanometry [1]. These are listed and defined in Table 6.1. No standard accepted nomenclature exists at present so the various alternatives in use are given.
| Special Techniques (Methods) | Property or conditions | Abbreviations |
|---|---|---|
| Thermodilatometry (Thermodilatometric Analysis) | dimension (negligible force) | TD |
| Static Force Thermomechanometry (Static Force Thermomechanical Analysis) | dimension (static force) | sf-TM and sf-TMA |
| Dynamic Force Thermomechanometry (Dynamic Force Thermomechanical Analysis) | dimension (dynamic force) | df-TM and df-TMA |
| Modulated Force Thermomechanometry (Modulated Force Thermomechanical Analysis) | dimension (modulated force) | mf-TM and mf-TMA |
The more familiar names for these techniques include Thermomechanical Analysis (TMA) and Dynamic Mechanical Analysis (DMA).

Measurement of the thermal expansion of solids and liquids is a classical physical technique known as dilatometry. When special emphasis is put on recording such dimensional changes as a function of temperature, during a controlled temperature programme, the technique is labelled thermodilatometry [1], [2] and is one of the special techniques derived from thermomechanometry. For solids, we can distinguish between linear and volume expansion, and instruments for measuring the length of a solid sample as a function of temperature are the most common.
Most solids expand on heating. Exceptions include vitreous silica and ZnS at low temperatures. The change in...
