Display of stress results along line/spline in shell model

Display of stress results along line/spline in shell model

Anonymous

Hello, everyone,


unfortunately the stress linearization tool for shell models does not work for me. Do I have to activate something under parameters? For example, that it shows me something after node selection? For a 3D mesh it works...

 

Another question concerns the evaluation of my results. Is there a possibility to draw a spline or a line and display fixed points on it? So that you could set probes (nodal probes) along this line.

 

A further question concerns the accuracy of the probes. When I set probes it only shows me the shell von Mises top/bottom stress. Is it possible to display in the nodal probes the Von Mises stress as if I activate "Show query" under "Nodes" in the model tree? The values for Top stress and Shell Von Mises are quite similar, but not the same.

 

I would be very happy about some help. Thanks!

Hello! Linearized stresses are calculated automatically for shells. You get bending and membrane stresses directly.

 

Another question: 
No, you cannot do this in Invetor Nastran. 

 

I didn't quite understand the further question. Could you explain it in more detail?

Hello,

 

This answer is based on Inventor 2020 and Inventor Nastran 2020.  I can't speak to earlier versions of the software.

 

With regard to your further question, the values displayed by the probes should reflect the values that you select to be displayed in the contour plot.  This is controlled by the drop down buttons at the top left of the modeling window (see attached photo).  In general, the probe should tell you the element number that you're looking at, the value(s) that are displayed in the contour plot, the total translation, and the coordinate translation values.

Hi,

 

thank you very much for your answer.

I had the idea to take different values of my result by the probes in a certain region. Then I wanted to calculate the average value from these values to compare it with different designs. Alternatively, I could simply use the maximum value for a calculation regarding the failure of the component. What would you prefer if you looked at a specific area of the component?
