If you are looking for experimental data for thermoplastics, take a look at the [url= http://polymerfem.com/index.php?pageid=mat_mod ]Materials and Models pages[/url].

The Materials and Models section contains both experimental data and predictions from different material models.

Hi, I am doing a numerical simulation of a steel bullet impact on Polycarbonate. I am using the ductile damage model from Experimentation and modeling of inclined ballistic impact in thick polycarbonate plates by A. Dorogoy et. al. The fracture strain and corresponding strain rate values are present. But I could not find the stress triaxiality values which are very essential for the simulation
[I]What are the stress triaxiality values for Polycarbonate?. Moreover, I am getting an exit velocity of 374m/s for an inlet velocity of 375m/s which is wrong. I dont know how to set it right. Please help me out.[/I]

It sounds like you may not have an accurate material model and/or failure model for PC.
Can you run some experiments on your specific PC?
