Thermomechanical Analysis (TMA) is one of the most fundamental analysis techniques as it measures a very basic property of materials. It measures softening the point or glass transition (Tg) as well as tests like Vicat and heat deflection point. All of these can be approximated in a Tg, and all tell you where a material changes from stiff to flexible. You can also measure the coefficient of thermal expansion, a property where, if mismanaged, can lead to failures in electronics, motors and food packaging.
