 Dear LS-DYNA Support Team, I hope you are doing well.

I would like to ask whether the yield locus model **YLD2004-18p** can be applied to **shell elements** in LS-DYNA.

Could you please let me know if this material model is supported for shell formulations, and if there are any specific limitations or requirements that need to be considered?

Thank you very much for your support.

 Best regards,

 Philipp

Hi, 

MAT_199_YLD2004 captures the yield criterion  where up to 18 material parameters define anisotropy for a 3D stress state.

This model is currently available for solid elements and thick shell formulations 3, 5, and 7. 

Cheers, Ram

Hello Philipp,
Please see the screenshot below from the LS-DYNA keyword manual R16. For shell elements, consider MAT_BARLAT_YLD2000 model (*MAT_133).
