WebPrinciple of Thermomechanical Analysis (TMA) Definitions of Thermomechanical Analysis (TMA) A technique in which a deformation of the sample under non-oscillating stress is monitored against time or temperature while the temperature of the sample, in a specified atmosphere, is programmed. WebDMA. Dynamic mechanical analysis (DMA) is an important technique used to measure the mechanical and viscoelastic properties of materials such as thermoplastics, thermosets, elastomers, ceramics and metals. In a Dynamic Mechanical Analyzer, the sample is subjected to a periodic stress in one of several different modes of deformation.
