What Does a Dynamic Mechanical Analyser (DMA) Measure and Calculate?
Precise Analysis of Mechanical and Viscoelastic Material Properties
In Dynamic Mechanical Analysis (DMA), force and displacement are measured directly using a high-precision load cell and displacement encoder. These accurate measurements enable reliable analysis of material behaviour under various loading conditions.
By analysing the phase shift between force and displacement, the viscoelastic properties of a material can be determined. Both the elastic and viscous components of material behaviour are taken into account.
The Dynamic Mechanical Analyser from Prescott Instruments enables the measurement, calculation and evaluation of a wide range of mechanical and dynamic material properties.
