Hi everyone,
I am trying to use bilinear isotropic properties for PLA in ansys for a model. I want to know tangent modulus value for PLA that can be used in Ansys. I dont know how to get the tangent modulus value. Is there anyone who can help me in this regard? As the stress-strain curve of PLA is downward in plastic region, even if I take a slope value from any point in plastic region, its negative and I can not use negative value in Ansys, it shows a yellow error. I am really stuck with this problem and can not proceed further. Any kind of advice is welcome. I really need it.
Thank you
Kind Regards
Aqib
