How does COMSOL handle Composite Materials issues in Solid Mechanics?

A multilayer composite material was simulated by using the Solid Mechanics module. The geometry forms union. So how does COMSOL deal with the stress between layers? For example, when calculating the stress of the nodes between layers, which layer's mechanical parameters should be used.

The default result on a boundary would be the average between the two domains.
If you want evaluate results that are discontinuous, you can use the side() operator; side(domain_number,expression).
Another variant is up(expression) and down(expression), but then you first have to figure out which side that is 'up' and which is 'down'. One way of doing that is to create a surface arrow plot of the surface normal vectors.

Got. Thank you again!
