Hello Henrique,
Yes, you would insert a body to represent the glue, at whatever thickness is selected. Use 4 elements through the thickness. Use Shared Topology to connect each side of the glue to the diamond or steel. Now you need material properties for the glue.
Cohesive Zone Modeling is useful for studying failure, but you want an analysis that shows no failure so CZM is less useful to you.
