Flexible hinges - enforced displacement

Altair Forum User

Hello everybody,

 

i'm trying to deform a flexible hinge with the enforced displacement. The Problem is, i only can apply a displacement in a single direction but i want to fold the hinge.

Here is a picture of a flexible hinge

I know the deformation but i dont know the stress or force.

 

Maybe someone can help?

 

Thanks in advance.

You can apply enforce displacement on both faces & run analysis.

 thanks for the reply.

I'm pretty new to inspire and FEM and testing something out for my thesis work.

i don't really know what you mean. Here's a screenshot. Maybe you mean different faces?

Here's a picture of what i try to do. Maybe inspire is not the right solution and i should go with another programm?

Inspire is meant for quick topology optimization & basic analysis like Static & modal analysis for design validation.

From the above picture i feel you should use Radioss or Optistruct solver for such large displacement problem.
