Good morning to every body,

I'd like to make a realistic simulation of a 3D printed material (ABS) reinforced with carbon fiber. So a very anisotropic material. There are any suggestions you can give me on how deal with the resistent of each layer, for example the selection of material or anything else ?

 

Thank you

    By reinforcement you mean short fiber reinforcement or long fiber?

    I would say it is not so trivial to model the behavior of 3d printed materials, and you would need to calibrate well your material properties.

    What kind of behavior do you want to capture?

    For stiffness and linear effects you might use OptiStruct and create a homogenized anisotropic material with the orientation of the layers.

     

    But for more accurate modelling, including material failure and delamination you might want to use multiscale designer (MDS) or Radioss.

     

    In MDS you can model the fiber and abs matrix in more details and you can use test data to calibrate your material properties.

     

    Good luck with your projéct!
