What you mean by shared topology? If I have some layers that is in bonded contact, can I replace it with shared topology? Will it give same result, if we do any type of structural analysis(like bending, twisting, tension etc.)?

Bonded contact is useful if you want to study failure of the interface between layers.  Search for Cohesive Zone Model.

If all you want is to have the load transfer from one layer to the next, then shared topology allows the two layers to share nodes at the interface.

Here is a little longer description.

In the discussion above, actually I want to find out the normal strain in the 1micrometer layer during the twisting of the whole layer. So if we use shared topology instead of bonded contact the result may change? Also when I tried with bonded contact, the solver doesn't converge. So is there any method to rectify the problem.? In actual case the layers are in bonded contact with each other

[peteroznewman]

With either shared topology or bonded contact, you can plot the strain of just one body, separate from the adjacent bodies.

The results can change a little from shared topology to bonded contact because the contact elements have their own properties. It is cleaner to use shared topology.

What direction are you calling normal?

I mean the x-axis in the discussed case(4layered sheet)
