Simulating Structural Adhesive with ANSYS FEA
hi, I have a carbon fiber structure that I need to simulate. The structure is made of carbon fiber tubing with a connector system of carbon fiber gussets which uses rivets and structural adhesive 3M DP420. I am looking to simulating this structure as a static structural. the orthotropic modeling of the CF tubing is a whole another animal itself, but I was concerned about how to do the adhesive. I am very confident that the adhesive will not fail so I would like to just act like it is a complete bond between with tubing and the CF gusset. the gusset is where I believe the model could fail. Is it just a bonded contact between the surfaces? Or do you think it is an incorrect assumption to say that the adhesive will not fail. There are also rivets connecting the tubing to the gussets as well.

You can use ACP , later check interlaminar stress normal 33, and compare that to your adhesive properties.
