Hi all,

I am trying to find a way to take into account local buckling in Class IV sections in Abaqus. This can be done in SAFIR via recalculating the material plasticity under compression, like Franssen et al. in "Effective stress method to be used in beam finite elements to take local instabilities into account" but I cannot find a way to implement a similar method in Abaqus.

I would appreciate very much if someone can give me a hint about this matter or point me in the right direction with some publication.

Thanks in advanced,
