I am currently trying to characterize the behaviour of different plastic polymers, in particular when stretched in an uniaxial direction.
I already conducted the classic tensile test, and got a general idea of the different features that the materials show, but I am having a hard time trying to measure their stretching stiffness; any suggestions on lab tests for this?
I found an equation linking stiffness to the elastic modulus and the resisting cross section, but I`d rather find it in a different way so as to not refer to a single type of test for all of my data.

ISO 178 provides the standard dimensions and conditions for tensile testing. Most important for you is the elastic modulus. Depending on the intended application of your material, 3-point flexural testing (ISO 527) may be more appropriate. You may also wish to consider the application, when choosing an appropriate testing speed. Good luck.
Thanks for the suggestion, I found the article very interesting, but I dont think it is what I was looking for, I am not handling nanofilms, so I dont have the right tools, furthermore I guess I wouldnt be able to get some results out of the test with such a thick material.
If you have any other suggestions please share, thanks again.
