Workbench - Variable beam cross section

Workbench - Variable beam cross section

Workbench - Variable beam cross section

(OP)
Hi,

I'm trying to do a beam with variable cross-section in ANSYS Workbench using the DesignModeler.

I create the inicial and final cross-section, but I can only choose one of them in the Line Body proprieties.

Does anyone know how to choose both or how to do this inside Workbench Mechanical?

Thanks

RE: Workbench - Variable beam cross section

Hi there,

when i do beams of varying X-section i create sketches of the specific X-section dimensions at differet planes. Then i select the "Skin/Loft" option. Then i Ctrl + select the specific sketches in the Tree Outline and generate. See attached picture.

Regards

kranmeste,

Thank you for your help, but i`m doing a Static Structural Analysis with this beam.

The "Skin/Loft" option transforms the beam body into a solid body, and it uses solid elements when I do the analysis, in the end it doesn't show the results that i`m looking for.

I need a method of "beam with variable cross-section" that uses beam elements in the Static Structural Analysis (like BEAM189 or BEAM188) with ANSYS Workbench.

Thanks

RE: Workbench - Variable beam cross section

Hi,

To my knowledge the cross section can only be prismatic when using beam elements in Workbench. So if i were to make a beam with varying cross section i would divide the total length of the beam into minor divisions and then adjust the cross section for each division. So the beam would look like a pyramid with all the steps. If you find a better method for making variable cross section using beam elements, please do post this.

Regards
