Simulation of composite laminates

Hi all,

Do you have any idea of modeling (simulation) of laminates , e.g. bi-layer composites having layers with different elastic modulus avoiding the so called 'free edge effect' (a stress singularity at the free edge).

i am using Comsol 4.3b and having this problem while i try to work with modeling creep in bi-layers

thanks for your time
