How to avoid distortion of a CZM layer as well as the penetration of a soft slave matrix to a stiff fiber during sandwiching the CZM layer in ABAQUS?

Hello, I am modeling the adhesion between a carbon fiber and a soft matrix by a CZM layer (Fig 1). Due to transversely cutting the elements, a compressive load sandwiches the elements (fiber and...

How to opt a proper density value for a Cohesive zone model (CZM) in ABAQUS Explicit?

I am modeling a single CZM layer (E=2 MPa) at the interface of a fiber (E=242GPa) and a soft matrix (E=2 MPa). The question I have is how can I define a proper value for the density of the CZM layer.

What is the best part geometry (sold or shell) to model a cohesive layer as the bonding property between two parts in ABAQUS explicit?

I am modeling the cohesive property between a carbon fiber of 7 um diameter that is located in the center of a 1mm cylindrical PDMS matrix. My question is which part shape (solid or shell) can be...
