3D Composite model in ABAQUS
Wed, 2009-11-25 12:38 - parimal_maity
Dear Abaqus Users,
I would like to model 3D composite structures using Hashin Damage model in ABAQUS. I have seen in ABAQUS manual that Hashin damage model is applicable only for shell element. I would like know whether I can use 3D element available in ABAQUS. Any help would be higly appreciated.

continuum shell element
The Hansim damage initiation criteria must be used with elements with a plane stress formulation, which include plane stress, shell, continuum shell, and membrane elements.
I suggest you use the continuum shell element which costs less computation than solid element but the effect is almost the same.

Continuum shell vs solid elements
Hello,
I know that this post is quite old but I was wondering if you could tell me a little bit more about the difference between SOLID and CONTINUUM SHELL elements.
I am asking this because I used Abaqus/CAE to simulate a delamination between two plates using solid and continuum shell elements (with a cohesive behavior surface interaction between them).
I could see a crack propagation in the continuum shell case but not in the solid one (the platestips bendend a lot but the crack did not propagate). It was like the plates modeled with continuum shell elements were stiffer than the ones modeled with solid elements.
I used exactely the same properties for the plates and the interaction between them. I also used more or less the same element size for the two cases.
Do you know why this is happening?
Thank you for your time and attention.
Best regards,
David Melo
