Dynamic Mechanical Analysis (DMA)- Polymer Characterization

Dynamic Mechanical Analysis (DMA) is a frequently used technique in materials characterization. It is most useful for studying the viscoelastic behavior of polymers. DMA mechanically deforms a sample and measures the sample response as a function of temperature, time, frequency and amplitude. The DMA measurements are used mainly to determine glass transition temperature, modulus, damping behavior, relaxation behavior, molecular interactions, creep recovery, degree of cross linking, crystallinity, and effect of fillers on material’s properties.

Thank you so much. It was the most understandable method to describe DMA (which is so hard to understand in the beginning). It was amazing and so useful

Very nice video! Informative, clear, and to the point. I am definitely recommending your channel to my co-workers! Thank you so much ❤️

Thank you so much for this video! That was a great explanation. This was really helpful for my Characterization class.

It is well explained. Thanks for taking the effort to prepare and deliver the presentation.

This is what i was looking for
Thank you so much for your lovely content

Your lecture is very helpful to understand stand my analytical works

[shaikshakeeurrahaman]

Thank you so much for your detailed explanation. Will the result analysis be the same for other materials too or just only restrained to the polymers only? I want to apply the same for Cement Asphalt Mortars? So will it be applicable or not?

Thank you so much!! This lecture was so clear and helped me understand things I couldn't by reading only. A melody to my ears!

How can I determinate the melting point on a typical DMA Scan?

This year XE ppr was very out. Numerical was tough.

[vittoriocarino]

someone can explain to me why loss modulus decrease in rubbery state

[lemtalsiinas]

Can you prose me a book that's more focused on this area at live for my thesis. 
thank

Hi, You should use words wisely. We cant use strain and deformation interchangeably. It's technically incorrect.
