Avoid Plastic Failure - The Use of Dynamic Mechanical Analysis

Dynamic Mechanical Analysis (DMA) is a thermos-analytical 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. Made with long molecular chains, polymers have unique viscoelastic properties, combining both elastic solid and Newtonian fluid properties. 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

In this program by expert speaker Jeffrey A. Jansen, you will understand how to evaluate the effect of temperature on the mechanical properties of plastics and other polymeric materials through DMA. This webinar will illustrate the time and temperature act on plastic materials in the same way and explain the use of DMA to project the effect of time on plastic materials.

You will get an introductory look into DMA and how it can be applied to better understand plastic behavior, both long-term and short-term. Creep rupture is a leading cause of plastic component failure. By understanding how dynamic mechanical analysis can be used to predict the effective lifetime of a plastic component, failure can be avoided.
