Composites Modeling: Conventional/Continum shells

Composites Modeling: Conventional/Continum shells

Composites Modeling: Conventional/Continum shells

(OP)
Hello,
I am trying to model a foam core/carbon epoxy skin sandwich specimen for static stress analysis (in three point bending) in ABAQUS 6.8-2/Standard.

In my model, I have the foam core as solid and skins as shells sitting right on top of the foam core (No gaps/offsets) in the assembly. The skin is tied to the core during analysis using geometric tie constraints.

I created a continuum shell section with the correct layup. When applying the section properties to the skin, what should I set the offset parameter to in this situation?

In general, can someone explain me what the offset parameter and reference surface mean for conventional shells and continuum shells?
Thanks
 

RE: Composites Modeling: Conventional/Continum shells

You would find a detailed description of reference surface and offset parameter in Abaqus analysis user's manual, Section 25.6.3 (Abaqus 6.9).
