Creating Cohesive Elements

To model adhesives, interfaces in composite materials or crack propagation, it is possible to create cohesive elements.
A geometry with highlighted surface indicating location for cohesive elements

The above example has a shared surface between the green and yellow volumes which is already cracked, using the unmerge command in Cubit. The highlighted merged surface can then used for creating cohesive elements. The following command will do so.

Create Cohesive Elements Block <value> Surface <ids>

The Block keyword indicates the block id for the newly created block.

The Surface keyword indicates which surfaces to unmerge and insert cohesive elements..
