hi guys,

 

i want to only see von mises Stress of  Beam (1 D) in HyperView.

 

but i donot know, how to do that in hyperview or hyperworks?

 

Thanks for your help.

Hi 9527kun

 

HyperView currently don't support stress for 1D elements. Stress/Strain are available for solid and shell elements till the current version. 

 

This may available in future versions of HyperWorks.

Hey,

 

I am going to update here because I ran into the same problem and hit a solution after a lot of trial and error.

 

The things that solved it for me was to use the PBARL property card instead of the PBAR property card. I am hoping there is an analogous card called PBEAML as well.

After this make sure that you are using the 'Standard section Library' = Optistruct, this should give you the Von Mises for 1D elements.

 

<If posting a screenshot on this forum were easy I would post one>

 

Make sure yo have the Stress = Yes output request switched on of the load step.

Hi All,

In OptiStruct v13.0, CBAR/CBEAM(PBARL/PBEAML) Stresses at evaluation points are output separately (different from PBAR/PBEAM-element) in H3D file. When you load h3d result file in HyperView, you can see a new result type like 'CBAR/CBEAM Stresses (BAR)', 'BAR' in the parentheses is the type name of beam cross section. That means each cross-section type has its own result group. 
And you can review all the evaluation stresses (normal, shear, and von Mises) for each cross-section type, at each element end (A or B ). 

For instance, 
Normal S3N(/emoticons/default_cool.png' alt='B)'> : means normal stress at the 3-th evaluation point of the beam element end B; 
Shear S6S(A) : means shear stress at the 6-th evaluation point of the beam element end A; 
von Mises S5V(/emoticons/default_cool.png' alt='B)'> : means von Mises stress at the 5-th evaluation point of the beam element end B. 

And you can see maximum normal/shear/vonMises stress at the end.
