Question in ABAQUS

Question in ABAQUS

Question in ABAQUS

(OP)
Dear All,

I modeled a sandwich panel in ABAQUS. The pane thickness is 4.15 inch and the facing's thickness is 0.09 in. I modeled the core and facings using solid elements (C3DR) and results were in good agreement with experimental results.
However, I am wondering is there a good arrgument to support my assumption that solid elements can be used to model the facing instead of using shell elements. I know that solid elements would require longer time to run as lots of elements are needed to maintain the aspect ratio in 3D direction. But since the work is already done and don't want to redo it to my client, your input would be appreciated.

Thanks!

RE: Question in ABAQUS

yes i think it is more typical practice to model the facing with shell elements ... you must've had a boat load of TETs !

or you can model the whole sandwich panel as a laminate plate element.

another day in paradise, or is paradise one day closer ?
