Hi,

I have a working VUMAT, but I am unable to run a simulation of a composite plate in Abaqus/Explicit. From what I understand, I can’t use the composite layup feature in Abaqus explicit with solid elements. How should I model my plate then? Thank you

Hello. You can only simulate the elastic behavior of composite material with a 3D continuum element with a special method. You should use the hemogenous section. Then, assign a material orientation to specify fiber and matrix direction. If you want to model failure or damage behavior for 3d composite material, you need to write the subroutine. Some subroutines are available in the shop.

    Ok I see. So, I model every ply as an homogenous section and then constrain them together? Or if I partition the plate through the thickness I can assign each partition an homogenous section? Thank you

The second method is common
