How can I connect the zero thickness cohesive element in between inclusion and matrix because when cohesive elements thickness is zero we cannot use tie constraint option to connect top and bottom surface of the cohesive element. Even if you connect the same surface on both inclusion and matrix ABAQUS will throw an error message stating that using same cohesive node more than once in the tie constraint provide erro.
In order to avoid this we can use sharing node option but the problem which I am encountering here is that the seed size between matrix and interface is not constant, on the other hand I was not able to see stack direction of the cohesive element after making the thickness of the cohesive element zero . Guys please let me know some idea to use the sharing node option between inclusion and interface as well as matrix and interface in the case of elements size between them.
