Multi linear isotropic Vs. viscoelastic / viscoplastic for POM polymer

Multi linear isotropic Vs. viscoelastic / viscoplastic for POM polymer

Multi linear isotropic Vs. viscoelastic / viscoplastic for POM polymer

(OP)
Hi all,

I am looking for a long time for the best suited material model for POM polymer.
Currently the only test data I have is uniaxial stress strain curves in various strain rates, and I am building multi-linear isotropic material with the data I have and I am using different data (i.e measured in different strain rates) for different analysis that simulates different strain rates in real life.
I was reading about viscoelastic and viscoplastic material models and didnt quite understood what test data should I have and how to use these models in ANSYS structural.
My first question is : does my current method (multi linear with different curves for different strain rates) seems logical to you?
Second question : I was looking for some guide/manual/training material in the ANSYS portal on viscoelastic and viscoplastic modeling and couldnt find anything usefull, can some one send me to the right direction on this?

Thanks.

RE: Multi linear isotropic Vs. viscoelastic / viscoplastic for POM polymer

Hello,
Regarding your second question, you can find in the Ansys portal the training on viscoelastic and viscoplastic modelling by searching "nonlinear materials".
