Material model for thermoset for impact simulation (ANSYS)

Hi Jorgen,

I am new to plastics. I have to simulate an impact test on thermoset plastic specimen using ANSYS. I am unable to figure out what kind of material model to be used. As we use rate-independent plasticity models in metal plasticity mostly Mises-plasticity are there any model to simulate rate-independent plasticity in thermosets. Or should I look for rate-dependent plasticity and things like that then what are choices in ANSYS. I went through the help but could not figure out any specific models for polyemers. Any tips will be highly appreciated.

If your simulation does not need to be very accurate then you can use a simple rate-independent plasticity model. If you want more accuracy then you can use a rate-dependent plasticity model, or if you want really accurate results then you can use an advanced material model such as the [URL= https://polymerfem.com/index.php?pageid=umats]three-network model[/URL].

What type of experimental data do you have available?
