Dear guys,

I am somehow new member here and would be happy to hear from your side more.

I am planning to do some [U][/U][B]high strain loading tensile tests [/B]to obtain material characteristics of such kind of polymer-based materials.

In this way, I can achieve the material properties such as elastic modules, failure stress and etc. But I am very interested to find an approach to formulate the [U][/U][B]resulting stresses [/B]based on the [B][/B][U]resulting strain [/U]and [B][/B][U]strain rate [/U]values as well.

Does somebody have any previous experience, idea or reference?

I would be pleased to hear from your side.

Thanks,

Hani

I like high strain rate tests, but I dont understand your question 🙁

Dear Jorgen,

I want to find a constitutive model for the output of my high strain rate test as below:
[SIZE=4]&#963,=C1 [B]&#1013,[/B]+C2 [B]&#1013, [/B][/SIZE]&#775,

for more explanation, you suppose I am doing a test in high strain rate ([B] &#1013, &#775, [/B]) and my resulting stresses ([B]&#963,[/B]) and deformation ([B]&#1013,[/B]) are achieved by data acquisition system. So, in this case, I am interested to model the achieved stress-strain curve by Strain plus to strain rate as well, same the above-mentioned formulation.

I would be really happy to hear something helpful from your side.

Many thanks,
Hani
