loading 1

[nicolasdegand]

Hi,

In the case of a 3D plate perforated by holes. I'd like to apply a linear load (perpendicular to the plate) to the circle defining the hole (circle with a diameter equal to the hole diameter). So I'd like to select this circle after selecting the "line load" but I just can select bodies. I don't know how to do???

Thanks a lot

Nico

I think you should use Create Load -> "Shell edge load" (in CAE environment) and set 'Traction: Transverse' if your plate is in 1-2 plane or better set 'Traction: General' and define the direction vector by two points.

hi xerf,

I don't have in (create>load) "shell edge load", I only have:
-pressure
-body force
-line load
-bolt load

which could apply in my case.

I suspect your version is other than 6.5.

I am not sure there is a direct approach of distributing force over nodes. If suitable you can use one of these approaces:

1. create a (very) small annular partition near the hole's edge. You can use 'Pressure' with this new partition since it is surface-like region.

2. partition the hole's edge by creating a sufficient number of vertices on it. Make a set from all these vertices. Apply concentrated force on this set. In this case you will have to adjust the (concentrated) force magnitude to behave like a distributed one.

In 6.5 they introduced "Shell edge load" , where you can directly apply tractions on shell's edges.
