Amin Al-Fakih, In order to use these elements in Workbench Mechanical, you'll first model the Gasket as a solid body. Not as an interface like you have defined currently.

Then you'll have to specify appropriate Gasket properties in the engineering data:

And finally, then you can set the stiffness behavior of the solid which is a modeled as Gasket in the Mechanical as follows:

Then the elements in the solid will be modeled as INTER194.

One thing I noticed after typing this up, is inter194 will only work with enterprise license, I am not sure if that will work at your end as your license seems like Academic.
