Shell Edge Load Application on a Plate 1

[FEAMonkey]

Hi Everyone,

I have modelled a 3D plate using shell elements in Abaqus. I have applied a fixture to the bottom edge and load on the top edge of the plate. The setup and the result of the analysis:

As you can see, the top edge of the plate where the load is applied is curved in the direction of the load. In reality, the load is applied by a big clamp which pulls the whole edge up. Therefore, in the simulation result my deformed shape should show straight top and bottom edges.
How can I apply the load in the appropriate way?

Thanks for your help.

Create a kinematic coupling on the top edge and apply the load to the reference node of the coupling.

 

[FEA way]

You can use kinematic coupling or rigid body constraint to apply this load. Second option might be preferable in this case

Thank you for your quick response.

I have applied a rigid body constraint on the top edge with "Pin" region type.
It seems to work well.

Can someone give me a scientific reason why the maximum stress is lower when the rigid body constraint is applied on the top edge?

A view on the right image you've posted should explain that.
