Composite Analysis Transverse Loading

Hellow All,


I have been using simulation reguarly to model isotropic carbon composite sheets and it works spelndidly but in doing so I am always appling loads to the face of the shell.  Now I am trying to model a condition where I have a carbon composite sheet and I have a bolt going through it.  I am concerned about tear out and trying to specify wall thickeness. As a results the loads are now plane with the face and applied to the hole edge, bearing loads.  The results I am getting are far off the mark.  I have also tried builing an aseembly and apply loads to solid bolts with a no pentration condition between the shell and the bolts but that does not seem to work either.  Any suggestions?
