Description
Dynamic mechanical analysis (DMA) measures the modulus (stiffness) and damping (energy dissipation) properties of materials as the materials are deformed under periodic stress. Such measurements provide quantitative and qualitative information about the performance of the materials. DMA can be used to evaluate a wide variety of material types (elastomers, thermoplastics,
viscous thermosetting liquids, composites, coatings & adhesives, ceramics, metals). It is particularly useful for evaluating polymeric materials, which exhibit time, frequency, and temperature effects on mechanical properties because of their viscoelastic nature.
Specific material properties provided by DMA include modulus, damping, glass transition and softening temperatures, rate and degree of cure, viscosity, onset of gelation, sound absorption and impact resistance, creep, and stress relaxation. DMA results are used primarily in research and development for investigation into the structure of materials, material development and selection for specific end-use situations, competitive product evaluations and material lifetime performance evaluations. The technique is also used in quality control for process simulation and optimization, vendor certification, and troubleshooting.
