Analysis Output Controls for a shell object

Anonymous
Not applicable

Hi everyone,

 

let's say I want to display a simple bar in a static-linear analysis as a shell object. This is fixed at one side and is loaded on the other side by a force. Once I have specified my thickness (t), I can set various output controls under the analysis settings (picture).


What is the recommended setting for this simple analysis? Is a check mark at "Displacement" sufficient or is it recommended to activate "Applied Load" as well? What is the theoretical difference? Are there settings for shell objects that you recommend for a simple static linear bending analysis?

 

Furthermore I wanted to ask, if you think that Inventor Nastran can give approximate results when comparing displacement and Von Mises stress with increasing thickness (t=1,2,3,....n mm)?

 

Thanks!

Hi @Anonymous 

 

The options shown in your image are results that are output. In order to see the displacement results, you need to check the displacement output. In order to see the stress results, you need to check the stress output, and so on. You need to choose the output that is necessary to get the results you need to evaluate the design.

 

What options are choosen to output have no effect on the calculations.

 

For your last question about getting results with different thicknesses, the answer is yes. That is the advantage of shell elements. You just change a numerical input to change the design.
