The various deformation modes
Dilatometric mode (A): This is the mode most commonly used in ther- momechanical analysis. The expansion coefficient is determined as a function of temperature. A typical feature of this mode is that the probe exerts only a very small force on the sample.
Compression mode (A): In this mode, the sample is subjected to a large force.
Penetration mode (B): The purpose of a measurement in the penetra- tion mode is to determine the softening point of a sample. This is usu- ally performed using the ball-point probe.
Tension mode (C): The fiber or film accessory is used to perform mea- surements in tension. This allows you to determine changes in length due to shrinkage or expansion.
3-point bending mode (D): This mode is ideal for studying the elastici- ty of stiff samples such as fiber-reinforced polymers.
Swelling (E): Many substances swell when they come into contact with liquids. The resulting change in volume or length can be mea- sured using the swelling accessory.
Volume expansion (F): Liquids expand just like solids. A new acces- sory enables you to measure volume changes of liquids.
