Hi,
I am working with Glue contact in Patran/nastran between two shell plates(perpendicular), the aim of this contact is not to refine a mesh in case of detailed analysis. The finality is to get the same values when the mesh is coincident and when the mesh is not coincident and glue contact is used. My doubts are:
1-once the contact has been created, the next step is to define the contact subcase parameters, someone could explain me what kind of parameter must be selected to get the same results in a non-coincident mesh and in a conincident one? ERROR,BIAS, etc...?
2-I did a simply problem, with two shell plates perpendicular with the next parameters: Retain gaps, Retain moments, ICOORD, BIAS=0.9, ERROR=0, FRLIMIT=1E20, Ignore thickness and Free and hard shell (the other parameters are on default)
But when i run the analysis with different loading conditions, the fringe values are not so coincident, and the our glue contact model is not accurate enough.
I hope someone can explain me how to define a correct Glue Contact!!
Best regards
