I am making a model of a laminated glass panel, and I am now doing a 2D structure analysis of the problem.
The materials have a very large difference in shear modulus. Even if I use a very fine mesh, I get a result with a very large error (I checked the stress error plot).
Any idea on what I could do to solve this?
It is a layered beam on hinged supports loaded by a distributed load. The beam is a layered profile of 2 times 6 mm glass with 2 mm interlayer with a low shear modulus and a low elastic modulus.
I also tried nonlinear analysis, and this gives me unrealistic results ..

The error in the linear calculation is very large at the interface of the different materials:
