Material model for plastics is ANSYS

Now, let’s say you want to share your awesome material library with your co-workers, or maybe you’ve installed a new version of ANSYS and you want to include it, or maybe your library was deleted by gnomes during the night. How do you bring it back into Workbench? First make sure the xml file is available (you’ll want to email it. Jan 07, 2013 This feature is not available right now. Please try again later.
Hi,
The company I work for migrated to ANSYS lately.
I was using FEMAP as my pre/post with the NX advanced non linear code (ADINA) for implicit non linear analysis.
Our products are mainly made from polymers (POM, PEHD, and PA with and without GF) and I was using a simple plasitc stress-strain curve non linear material (data was based on tension test of injected dog bone samples). Althoug I know this is not the best model for analysis of plastic parts, this is waht I had at the time (from the point of view of material models in my FEA package, and from the point of view of the material testing data I had).
Now that we have migrated to ANSYS, I was wondering what is the best meatrial model ANSYS has to offer for such analysis types (I am talking mostly about nonlinear contact, nonlinear materials and geomteric nonlinearities such as large deflections and strains).
The main issue I am using the FEA tool is for validating assemblies (snaps, and undercuts) in plastics, failure of connections when for example inserting a tube on a nipple and so on.
For the purpose of the discussion lets say I have to scenarios:
1. I will have a talk with the R&D manager - and he will tell me no matter how much it will cost, do all the tests you need to get the best material model for all the resins we are using
2. I will talk with the R&D manager - and he will tell me - look, we just invested in this new software, use the equipment that you have (tensile test machine) and do your best without any work done by external labs.
What path should I take, what tests should I do, and what material models should I use for any of the above?
Thanks.

Hi, i'm facing an issue in Ansys Workbench. Upon clicking the cell to select material(Engineering Data) , the workbench is not loading an excel file with different materials and also the properties seems to be locked. I have attached a screenshot of the workbench.
Kindly Help.

hi! devaiah balluda ,
my ansys wokbanch also has same problem but I WONDERxC4xB0NG if xC4xB1 make your solution,AM I lost created analysis in ansys workbanch;;?

Well ,found the solution myself. It is a trivial issue most beginners like me face in the beginning.
