DCB test - CONTINUUM SHELL ELEMENTS vs SOLID ELEMENTS

Hello,

I modelled a 3-D DCB (Double Cantilever Beam) test specimen to simulate crack propagation (delamination) in composite materials.

To do so, I used surface cohesive properties between plates in Abaqus/Explicit, and applied a displacement at the plates tips.

When I used continuum shell elements the crack propagated as expected and the delamination occurred.
