Dynamic Mechanical Analysis of Glass Using Multiwave Tests

The use of Dynamic Mechanical Analysis (DMA) enables the characterization of glass from the solid, mainly elastic state towards the viscoelastic state during softening and reveals information about its mechanical behavior as a function of the temperature.

Glass is a versatile material which is of technological, scientific and economic importance. It is used for many different applications and for a wide range of products like containers, sheets, lenses, optical fibers and many more, where transparency and hardness are key requirements. The use of Dynamic Mechanical Analysis (DMA) enables the characterization of glass from the solid, mainly elastic state towards the viscoelastic state during softening and reveals information about its mechanical behavior as a function of the temperature. Viscoelastic materials show frequency dependent mechanical behavior during oscillatory deformation. Multiwave tests provide the opportunity to measure several frequencies simultaneously, thus to analyze temperature and frequency dependence within one single test.
