Thin box analysis

[Henrik_Lo]

Hi

I need some help making this analysis realistic

I have this box mounted to a wall with two ø8mm screws.

A load inside for 100kg.

How to make constrain right, and etc.

It is 1mm material, mild steel.

Can this box take 100 kg.

Regards

Henrik

Hi @Henrik_Lo 

You said that the box is mounted to the wall. Should you add a constraint at the bottom of the box and acting in the Y direction to stop the box from passing into the wall?

Here are some other changes you should make:

• Delete the Solid idealization. The model should only have the shell idealization and only have shell elements in the mesh.
• 100 kg does not produce a load of 100 N (unless you are designing this for Pluto at 0.07G). At 1G, the load should be 980 N.

Hi John

Thangs for replying

How about this then

I am not sure regarding the mesh elements how to change them to shell

You wrote "I am not sure regarding the mesh elements how to change them to shell".

You do not need to change anything to shell. The model already is creating shell elements because there is a shell idealization (and shell results). The problem is there is also a solid idealization which is creating solid elements. My suggestion is to delete the solid idealization and remesh the model. There will be no solid elements when there is no solid idealization.

Hi John

I will tray to delete all the solid idealization, and see what is coming out then.
