Introduction
DMA can detect and analyze viscoelastic variables like storage modulus,loss modulus,and loss tangent,as well as their dependence on temperature and frequency. The Tg and the temperature dependency of the modulus can both be studied via temperature dispersion. The test methodology of DMA, which aims mainly at the examination of solids, has its roots in rheology (see also “. Accelerated testing procedures based upon principles of time-temperature superpositioning proposed by Williams, Landel, and Ferry1 were devised to create “doubly-reduced” master curves of the observed mechanical response. Dynamic mechanical analysis (abbreviated DMA) is a technique used to study and characterize materials. Scope: Examples of standards: ASTM D4065, D4440, D5279 Results are typically provided as a.
