Creating "Equivalent Section" or specific mat. behavior with Abaqu

[freddanesi]

I wish to define shell properties which behavior is different
according to the sollicitation (membrane, bending, shear). I can only
define a homogeneous or laminate properties in Abaqus, but my behavior
is different. In Patran this behavior is called Equivalent Section,
and i give information about the material used in the membrane
behavior, the material used for the bending behavior and the material
used for shear behavior. In Ideas we can define this type of
properties in the same way. But i dont know how to do in Abaqus.
Thanks for suggestion.

The material is the material and I don't see how that can have an equivalent. If you're referring to the membrane/bending propertries then you must be specifying the area, and thickness (inertia), and shear factor separately as for a general beam section. For shell/plate elements I don't see the purpose of this at all. If it's not a thin shell or a general beam then model it differently instead of trying to fudge results to be similar to some other software.

You can enter the 21 ABD coefficients directly as data lines under a *SHELL GENERAL SECTION... This works when you omit the MATERIAL, COMPOSITE and USER parameters. Check the docs.
