simulation- fos - safety factor

[Hyper]

Good morning, I would like to know how to assess the resistance of a disk bound to the edges and with applied a perpendicular load to the flat face.

After launching the simulation, I can go to evaluate the fos.
In practice if I choose the "automatic" option, I'm asked to insert the multiplication factor.
I have a safety degree of 16 (frail material with repeated stresses), so the multiplication factor that is required I must report it as 1/16=0.0625? I have some confusion in my head.
What I'm going to get is a chart that I want to define the safe areas of the model, right?
thanks to all those who will help me.

No, you have to put 16.

 

[Hyper]

If I put 16 I go to multiply the value of the breaking load*16, then the chart I get should not be distorted?
if I multiply instead for 1/16 I should not have the value of the breaking load/16 and then I would go to evaluate the areas where this safety condition is verified?

1) do as I told you
2) read the help

 

[Hyper]

thanks for the solid straight.
I write the steps to make you assess their correctness:
1) ceramic material: fragile material -> in the safety factor section at point 1 of 3 selects "maximum normal solvent"

(2) point 2 of 3 — >
- "Stress limit tax on": yielding (chosen according to the fragile breakup of the material).
- multiplication factor: 16 (priced from tables for safety degrees)

3) "Safety Factor Distribution". Okay.

the result if it is all "blue" indicates that safety is respected, in case of "red" points the model must be changed, right?

Are the steps to follow correct?

Red dots can also stand there, depends on mesh and mesh.
However, I cannot tell you whether to accept them or not, not being my project and if you allow me it is your responsibility and responsibility.
I'm just here as a cad consultant.
I also wanted to remind you that the fem, although very reliable, is linked first of all to the values of the material, which must be verified absolutely, and then by how to impose the parameters.

 

[Hyper]

Yes, you were clear.
I was wondering if the procedure should be that, I didn't want to ask for info on how to evaluate the result of the simulation based on the parameters set etc. If it was interpreted so I apologize.
