DCB test - Continuum shell elements vs solid elements
I have modelled a [B]DCB (Double Cantilever Beam)[/B] test specimen to simulate crack propagation in composite materials.
I used interface surface properties between both plates and applied a displacement in the cracked tip of the plates (in Abaqus Explicit).
I used [B]continuum shell elements[/B] (shell homogeneous/composite section) for the plates and [U]viewed the crack propagation as expected[/U] but when I used [B]solid elements[/B] (solid homogeneous section) [U]the crack did not propagate[/U] and the tip plates deformed much more than in the continuum shell case.
[B]Can anyone explain me why this is happening?[/B]
Thank you for your help and attention.
