Hi,

I'm working on a packaging project, and i need to assign the SS curve of Liner and Fluting,

So how to declare the elasto-plastic behavior of corrugated cardboard Liner in (Machine Direction) and CD (Cross Direction) please! 

And the same for Fluting one.

Thank you in advance.

Hi Anoir,

To describe an anisotropic plastic behavior, you can check the Hill Yield Criterion in Engineering Data application (picture below).

Hi Armin_A, thank you for your answer, 

 

I'm working with an orthotropic material, i assigned the Hill criteerion but my material still not valide ?

[Erik Kostson]

Hi

So you need also bilinear isotropic hardening (Hill constants will scale that plasticity curve in the different dir.).

All the best

Hi Erik, Thank you for your answer, 

Even if i add bilinear isotropic hardening my material still not valide ? and desactivate the orthotropic properties.
