Comparing Solid element and Shell element - WB

Hi everyone, 

When I did an analysis for 2 cases: solid element and shell element in Workbench, I saw that the von Mises in 2 cases are much different

235 Mpa and 68 Mpa respectively. 

Figure 1: Solid element, VM stress 235 Mpa

Figure 2: Shell element, von Mises stress 68 Mpa

Could anyone take a look and send me any explanation?

Thanks in advance,

Hello Thanhttdt,

You have applied different loads to the two models.

On the Solid Model, you have a bearing load, which takes the force and applies it to the nodes only on the side of the face that a pin in the hole would push on, and with the force scaled as a cosine function with 1 on the centerline ramping down to 0 at the 90 degree point of the face.

On the Shell Model, you have a force load, which takes the force and divides it equally to all nodes around the circle.

Try putting a force load on the solid model and it will be closer. However, the bearing load is a more realistic load for your case.

Hi Peteroznewman,

Thanks for your suggestion, 

I try to use bearing load in shell element model but cannot.

Could you suggest me to apply bearing in this case?

Thanks in advance
