Is there a practical modeling for mapping the bearing?


The problem with bearing the hole is known that the force can only be transmitted by pressure. Train may not be transferred. It could be simulated as follows (see Figure 1):

1. Create opening in area

Second Create a bar with the nonlinearity " Failure at train ". It is important to use a beam bar and no push rod. A push rod is a truss rod. This would make the system kinematical.

Third Rotate and copy the bars

Alternatively, one could also close the opening with a face with the stiffness " membrane pull free " instead of the bars. When using this surface stiffness, the following happens:

The calculation takes place in several iterations. After the first iteration it is looked at in which surface elements for the main membrane tension occurs. These elements will fail in the next iteration (better said stiffness is greatly reduced). For both modeling variants one should get approximately the same results.
