COSMOSXpress Stress Analysis of Weldment

[ibro]

I want to do a stress analysis of weldment with COSMOSXpress. It seems that COSMOSXpress works only with part not with weldment. Any workaround? Is there way to "convert" weldment to one solid part? I am using SW2006.
Thanks,

Ibro V.

No work around that I'm aware of....COSMOSXpress is an introductory version of COSMOSWorks. Check you online help for what you can do in CE. I think you will need to have the Cosmos Professional to be able to do weldments because I believe it treats them as assemblies. I could be wrong on that because we use a different analysis program.

Heckler is correct. THere is no workaround Cosmos Express only works with a part only.

How about doing a Combine on the Cut List bodies? Not exactly the same as a weldment, but maybe close enough.

Blimey is correct in saying that while you cannot use cosxpress on an assembly or a multi-body part, you can combine the individual bodies into a single entitiy and run the analysis like that.

The one major problem with this method that "contact" areas will become solid, as if the part were welded with 100% penetration and no weld re-inforcement (the bead) and this would certainly be misleading as to the actual strength of the weldment.

Another method i have used in the past is to actually model the welds complete with penetration profile, and crown. In areas where necessary i have also modeled the melt through (such as the root pass of a v-butt weld).

You can use any method that you wish to model the beads, just make sure that you re-select the "merge result" option in the property manager.

Oh i should mention that if there are faces in the members of a weldment that touch, they too will join when using this method so you may want to cut-a little material so there is a small gap before you start modeling weld beads.

Just another option.

Best of luck
