I am trying to model a solid laminate with core as I don't think using PCOMP card accurately represents the torsional stiffness of the structure.
All I have is a shell model of the structure which is essentially a flat laminate. Then I have extruded the elements where the core is going to be and assigned the with the property for the core.
Now my problem is how do I taper the core. I have tried to use Mesh -> Editing -> Split but I think this is more for 2D elements. I basically want to split the rectangular elements diagonally, delete the edge elements so that the core has a taper and then put a top skin over the core.
Patran has both the solid element splitting functionality and the core skinning functionality. Can someomne please tell me the Femap equivalent if there is one or suggest another way to solve the problem.
Just providing some images showing the issue I am facing. If anyone has any suggestions please let me know. I have yet to figure out how to split the 3D elements diagonally and deleting some of them to model the edge. Then I am trying to skin the top face of the solid elements.
If anyone can provide some insight into the following questions:
A laminated part, subjected to both bending and torsion is modeled as
1) 2D Laminate (PCOMP: Layup has laminate plies and solid core all as 2D elements)
2) 2D Laminate encasing solid core elements (same layup as before but I have the top and bottom plies as PCOMP and the core as 3D solid elements)
would the results be different between the two?
