RE:Post processing visualization of stresses and integration points

[ryancwl95]

Hi there,

I am writing to enquire about the post processing visualization of stresses in my model. I am currently using a 8 nodded SSPbrickUP element to model a column of soil under pressure.

I am unable to view the stresses in the column. I have used the gauss point plot option to try to view the stresses in the soil column. However, I am unable to select the option of viewing the stresses.

I have also checked he analysis script, and it does includes the recorders for stress and strains.

how can i view the stresses and strains recorded from this model?

Hi, i believe found the answer in one of the past posts in the forum. is this the one?

That's because the SSP brick elements do not support the "material" keyword before the "stress" keyword (they have only 1 integration point)

So you can simply use the custom results an input "stress" only:

Hi, Yes you can use stress option as mentioned in the post.

Hi,

Thank you for your reply.

I was wondering if you could give a little more details on the components listed tin the results of 'Stress'.

In particular, is the pressure component listed in [E2]stress, the figure above, the same as the '[3] pressure' results under the results tab(figure shown below)? I am currently using using a SSPbrickUP element.

From the output results it doesn't look like the they referring to the same type of pressure. Could you provide a little more detail on it and perhaps the difference? There's little information in the documents and in the manuals. Thank you, your help is appreciated!

The last components in the stress result are useful stress invariants computed on-the-fly by STKO.
Instead, the pressure in the nodal result is the fluid pressure for U-P elements

[ryancwl95]

Do you know where i can get access to find out how these invariants are calculated by STKO?

[STKO Team]

You can google them, they are standard invariants

[ryancwl95]

Alright! thank you!

You're welcome

Dear STKO team,

I found how to see V in the elements of my model, but I need to see the values close to the nodes (as marked in violet in the picture "Taglio (1)"). I need them in order to perform the shear verifications.
Is it possible to extract a sort of table in which there are the shear values and the corresponding section?
If not, how can I get the shear values of beams and columns close to the nodes?

Thanks in advance
