Asymmetric stress strain response

Submitted by Ali Khajehgani on

Hello,

I need advice about how to model the asymmetric plastic response of POM in Abaqus?

The yield point in tension is 70mpa and 120mpa in compression. Also the elastic behaviour of the POM is very nonlinear and visco.

Please advice how to model these behaviors in Abaqus.

 

Best regards 

Ali
