ARAMID COMPOSITE SIMULATION 1

[Oluwakay]

Dear Colleague,
I trust you are fine. I have a scientific trouble I'd like to share with as I know you are an expert in composite modelling in Abaqus seeing from your previous responses. I tried to model aramid reinforced DCPD. I am able to define the aramid in term of the number of ply and I have the Johnson-cook damage data for the aramid and also the stress-strain characteristic of the DCPD. How can I define the matrix(DCPD) just to have it as a composite system? I'd appreciate a step-by-step way of achieving these if it is not too much for you to discuss. Thank you so much!
Regards.

There are different approaches to composite modeling in Abaqus. The article "Modelling a composite flanged tube including loading with Abaqus/CAE" nicely summarizes them. What you describe corresponds to a very common approach called mixed or mesoscale modeling. Each layer of a laminate is defined separately using a single material, usually with orthotropic/anisotropic elasticity, to form a composite layup. So layers are somewhat homogenized to include properties of matrix and reinforcement in a single material definition. Of course, fiber directions are defined for each layer to make use of anisotropic material behavior.

Thank you so very much for this piece. I will check out the article and try to apply it. Thanks once again!
