How to test the creep deformation of polymer

[Levy zhu]

Dear all, I am Levy , I am glade to take part into physics Forums, I hope I can share my know with everybody and study from you, Thank You!

I test the PET of creep deformation recent days, who has some reference about this aspect.

Thank you

Have you checked the literature?

Certainly, I have looked for some documents about the creep deformation, but no methods for the cord of polyester.

You missed ASTM D2990?

for your interest in studying the creep deformation of polymer. There are several methods that can be used to test this phenomenon, depending on the specific properties and characteristics of the polymer you are working with. Some common techniques include tensile testing, creep testing, and dynamic mechanical analysis (DMA).

Tensile testing involves applying a constant load to a polymer sample and measuring the resulting deformation over time. This can provide information about the material's creep behavior under a specific load and temperature.

Creep testing, on the other hand, involves applying a constant load for a longer period of time and measuring the resulting deformation. This can provide information about the material's long-term creep behavior and its resistance to deformation over time.

DMA is a more advanced technique that involves subjecting a polymer sample to a range of loads and frequencies to analyze its viscoelastic properties, including creep behavior. This method can provide more detailed information about the material's behavior under different conditions and can be useful for studying the effects of temperature and humidity on creep deformation.

It is important to carefully select the appropriate testing method based on the specific properties and application of your polymer. Additionally, it may be helpful to consult published research and literature for reference and guidance in conducting your experiments. I wish you success in your studies and welcome any further discussions on this topic. Thank you.
