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,

Could anyone see and give me any suggestions?

Many thanks,

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
