Dynamic Mechanical Analysis

December 5, 2024
11:00 AM to 12:00 PM EDT
Online

Summary

Dynamic Mechanical Analysis (DMA) is a thermoanalytical technique that measures the stiffness (modulus) and damping (tan delta) of polymeric materials to assess the viscoelastic properties as a function of time, temperature, and frequency. Polymeric materials display both elastic and viscous behavior simultaneously, and DMA can separate these responses. Polymers, composed of long molecular chains, have unique viscoelastic properties, which combine the characteristics of elastic solids and Newtonian fluids.

As part of the DMA evaluation, a small deformation is applied to a sample in a cyclic manner. This allows the material’s response to stress, temperature, and frequency to be studied. The analysis can be in several modes, including tension, shear, compression, torsion, and flexure. DMA is a very powerful tool for the analysis of plastics and can provide information regarding:

Modulus
Damping
Glass Transition
Softening Temperature
Creep Behavior
Stress Relaxation
Degree of Cure

This webinar will provide an introductory look into DMA and how it can be applied to better understand plastic behavior, both long-term and short-term.

Who Should Attend?

Are you developing products for long-term applications and need to predict the material's behavior quickly? DMA could be the answer.
Do you find yourself overwhelmed by the amount of testing equipment needed to characterize a plastic material and want to measure as many properties as possible with a single device? DMA is incredibly versatile!
Are you interested in understanding both the short-term behavior (modulus, softening temperature, degree of cure) and the long-term behavior (creep, stress relaxation) of a material? DMA can provide insights into both aspects!
