Hi,

There is no elastoplastic material model in the Beam interface. You will have to use the Shell or Solid Mechanics interface in the parts of the structure where the stresses may exceed the yield limit. You can then make transitiond to beam modeling in the rest of the structure.

Regards,
Henrik
