my dears,
please, how can i use cohesive element in ansys to simulate czm in shear mode test using ANSYS program?
is there any article explain this problem.

I'm sorry ,the link is not openning please, Possible to re-send again ,
You can use (cohesive zone material CZM) bilinear with traction and separation distance or with fracture energy. in ansys APDL you can insert a command for the CZM material and in workbench you can create a CZM material in the engineering data and input the parameters. you can model it as a simple surface and then obtain the parameter based on your surface conditions either from an experimental program if you conduct one, or from references and articles available in literature.
you can check the following references

First of all, CZM has variable approaches. You can read this link to decide which one is what you want to apply in your model.

I have worked in this topic for 3 years old. My problem was to create bond between two volumes. I have used "Bilinear Material Behavior with Tractions and Separation Distances".
Here is ansys codes but you have to calculate the six variables.
