How can I use hyperelastic to analyze beam(B31) model in Explicit from abaqus?

I want to use hyperelastic material to analyze B31 and solid model.
I want to analyze impact test, but have appear error.
The error message is Hyperelasticity or hyperfoam is not available with beam elements in Abaqus/Explicit.
How can I improve it?
Is it really can not analysis?

If you get that error message then I guess it is true :frown:

You can always implement it in your own UMAT.
