websites with stress-strain curve data for hiper-elastic material models

websites with stress-strain curve data for hiper-elastic material models

(OP)
Hi,

I need to run simulations in ANSYS Workbench with an hiper-elastic material. My question is: How can I get the stress strain curve points for different temperatures for PET? I think there must be some databases online, where it is possible to consult this type of data for different materials. I would like to have the link for those websites. I prefer free websites, but I am willing to pay if I don't get the information I want for free.



I appreciate your help,
Thanks in advance,
AndradeSilva

RE: websites with stress-strain curve data for hiper-elastic material models

What are you making and how? I'm not sure you need a hyper-elastic material model for PET, or that its even appropriate for PET. Pet is fairly stiff, and the elongation is not that great. At least as a first pass, a simple linear elastic or bi-linear isotropic hardening curve should work.

RE: websites with stress-strain curve data for hiper-elastic material models

I agree with Rick, if you want more accuracy you could use a multilinear model to define the material behaviour instead of hyper-elastic which is more propicious for rubber like materials.

Anyway, did you try to find stress-strain data in CampusPlastics? I have found some PET grades there.
