Hi,

I'm trying to model two objects sliding over each other within two blocks, that shear off at a certain load (roughly drawn up in attached screenshot).

I'm currently using an axial connector between two nodes on the objects, that I've set to be oriented towards the global Z axis, with connector stop and failure behaviours.

*ELEMENT, TYPE=CONN3D2, ELSET=STOPBREAKCON
1,1,2
*ORIENTATION, SYSTEM=RECTANGULAR, NAME=Z-AXIS
0.,0.,1., 0.,1.,0.
*CONNECTOR SECTION, ELSET=STOPBREAKCON, BEHAVIOR=STOPBREAKBEHAVIOR
AXIAL
Z-AXIS
*CONNECTOR BEHAVIOR, NAME=STOPBREAKBEHAVIOR
*CONNECTOR CONSTITUTIVE REFERENCE
0
*CONNECTOR STOP, COMPONENT=1
-10,5
*CONNECTOR FAILURE, COMPONENT=1
,,-1000,1000
*CONNECTOR FRICTION, COMPONENT=1, CONTACT FORCE=2
*FRICTION
0.3

The model isn't getting past the first iteration, and I've got it to solve without the connector so I know the issue is in here somewhere, can anyone tell me what I've done wrong to set up the connector or if there's a better way to model this interaction?

Thank you
