Metravib XPANDER Automated System for DMA

Dynamic Mechanical Analysis, or DMA, is a dynamic characterization technique that consists in applying a dynamic forced stress (or force) to a material specimen and measuring the resulting strain (displacement). Viscoelastic materials, like polymers, behave both like an elastic solid and a viscous fluid.

DMA measures the viscoelastic properties under dynamic oscillatory (often sinusoidal) test conditions. This test provides critical performance data for tire rubber compounds and other high performance composites.

Join us online with Guest Speaker, Hugues Baurier, in learning about how Metravib drives innovation in DMA analysis with higher force and frequency options. We’ll provide an introduction to DMA analysis in providing some case highlights and speak to newer innovations including the ability characterize elastomers’ resistance to tearing.

A new methodology has been defined for crack propagation analysis. The principle of the crack growth test consists in initiating a crack on one side of the elastomer film specimen, and following up the growth of the crack using an optical system focusing on the tip of the crack during a dynamic mechanical fatigue.

In this webinar, we’ll additionally highlight new automation options available in DMA characterization with the introduction of the Xpander, the new automated specimen handling system dedicated to Dynamic Mechanical Analyzers of DMA+ series.
