Compression implies a force pressing the two faces that contact together.


Tension implies a force that pulls the two faces apart.


If there is some adhesion at the interface, that is where the CZM with a Bonded Contact can model the peeling apart of the faces at the interface under a tensile load.


It would help if you Insert an Image of the geometry and point out the interface and which direction the forces are being applied.
