Material Models Database?
Material Models Database?
(OP)
Hi,
I was wondering if anyone knew any places to get raw data for standard materials. For example, I am trying to investigate contact deformation of Steel 4340 (standard material) but the stresses get way to high for the linear models that Ansys accepts. I have used the TB command before and this is what I want to do now.
I just dont want to have to run tests to get material stress/strain data. It seems like there should be a relatively easy place to get this data on the web!
Thanks!!!

I prefer to always use a detailed nonlinear model when I am expecting higher deformations.

You can use theoretical ramberg-osgood or practical stress-strain curves from literature.

Is it always better to use a nonlinear model in conjunction with the linear model (such as multilinear kinematic or bilinear hardening)? Will this always yield better results, especially when large deformation is expected?
