milling one piece made of two different materials

[JuKnip]

hey guys, I'm having a problem here and I hope you could help me.

What I'm trying to do is a 2D micromilling in ABAQUS Explicit. The geometry of the piece is a rectangle, and it'll be deformed by the tool. The thing is, I created partitions on the piece to associate each partition to a different material (in this case two materials), they were meshed,but when I simulate, each partition is considered as a different part, when I want to simulate the piece as one.
I tried using kinematic coupling and other constraints, but I'm not getting anywhere yet. Do anyone have any ideas?

How you figured that each partition is considered as a different part?

When I submitted the simulation, it was like the first partition (which was one material) pushed the other partition breaking it, like they were different parts and they weren't connected even by the mesh. I was expecting that the first partition would deform and push the other partition with the mesh still connected.
