    bilinear (elastic plastic ) behavior with hardening

    I need to model bilinear (elastic plastic ) behavior with hardening. (something like this... http://www.it.cas.cz/manual/pmd/pmdexman/img171.gif Can I to this using connector elements in ABAQUS. (I have the values for yield force and K values for pre- and post-yield regions.)

    Wen model in ABAQUS

    I will try to explain my problem more clearly. I have a 5 storey MDOF system with an NZ type base isolator at the bottom (fig.2). The force deformation (hysterisis) behavior of this isolator is represented by Bouc-wen bilinear model (fig.1). How to create this non-linear beahviour in ABAQUS. The...

    Wen model in ABAQUS

    I need to model base isolators(N-Z and Wire rope) in ABAQUS. The behaviour of these isolators is goverened by Wen model. I have tried connector elements using plastic + damping behaviour, however I m unable to get accurate results. Is there any other way of simulating Wen model in ABAQUS. I have...
