Please refer - Sandwich simulation> Quarter NL core contact> Run 35
Aim is to simulate displacement controlled compression test conducted on UTM and get the reaction loads. Quarter model is being used to reduce time of computation.
This is the displacement setting. Top face has been chosen to apply displacement.
This is the fixed support setting. Bottom face is assigned.
Previously bottom plate was volume assigned (partbody). Changed to face assignment inorder to get non zero values of reaction ([reason for volume to face assignment])(Unexpected Reaction force results - #5 by tsite).
I am trying to reduce the complexity of the set-up by applying constraint on the horizontal face of the plate in the core of the sandwich(curved plates).
Contact between the core plates is non linear ( physical contact).
These faces have been chosen to be applied with boundary condition such that stay horizontal. Only one side of the core is chosen for this so as to not form singularity through over-constraint as contact is already present between such two faces between the cores.
I would like to know if the way i am doing it is correct.
Rotation motion boundary condition applied on these faces with axis direction X and Y ( two different instances). Constant value of zero is given. Not sure about the base point though. How does this affect the rotation. Have chosen 0,0,0 to start with.
For run 35 the top core faces are chosen. For run 37 the bottom core faces are assigned for the above mentioned boundary condition.
Could I know if this boundary condition will keep the faces chosen horizontal throughout the simulation?
In run 36 have tried fixing the bottom horizontal faces of the core in the x and y direction , free in z. This is also another attempt to reduce complexity.
