Hello everyone,

 

We are working on a car chassis for a University Project Team. Chassis is made from carbonfibre composites. We put together support parts and main chassis with using adhesives (like Pleksus).

 

We are running structural analysis by using Hypermesh-Obtistruct.

 

So here is the question, what is the proper way to model composite - adhesive - composite connections? I have tried adhesive connector, but it is just filling the gaps with rbe3s. I want to connect composite parts with adhesive that i have the mechanical properties.

 

For better understanding, i am attaching two pictures, our past car chassis and a composite model to try adhesive connection.

 

Thanks for your supports.

Have a nice day.
