Material modelling: Drucker Prager and Crushable foam

Material modelling: Drucker Prager and Crushable foam

(OP)
Hi all,

I am using ABAQUS explicit to model a sandwich core material that consists of  a lot of fibres aligned at small angles to the metallic faceplates. I used the continuum element to model this core. Because this material is plastic pressure dependent, I cannot use VonMises and J2 flow law to model the material plasticity. So I used both Drucker prager and Crushable foam to model the plasticity behavior. However, these is a drawback in both models that is only linear isotropic elasticity behavior is permitted for the material; this does not correspond to the present transversely isotropic material behavior.

Any suggestion is appreciated.
