Stresses at the contact between two plates from different materials

Hello,

I have the following problem: 2 plates, one of steel, and one of composite (the ratio between the Elasticity modulus (E) is 10). The composite is glued on the the steel plate. When I load the steel plate, because it is glued, the composite is loaded too. My problem is that at the area where the two connect, I find the same stresses on both, while I was expecting to find stresses ten times smaller on the composite (that is a discontinuity between the two parts).

Where am I mistaking?

Many thanks

Re: Stresses at the contact between two plates from different materials

To be more confused, I add to the problem another mistery:

Even If I make the elements smaller and smaller, the difference between Nodal end Elemental strasses are still big (a ratio of 2, in favour of the nodal stresses).

As far as the initial question, it seems that if I use Elemental stresses, but not averaged, the difference between the stresses on the steel and composite respect the raion between the Elastic modulus (10)

Many thanks

Me again,

Could anyone make me understant the meaning of the term grid point? For example in the output request, you can chosse between Center or Corner grid points.

Many thanks
