# Thread: CosmosWorks, h-beam deformation

1. ## CosmosWorks, h-beam deformation

Hello people.
I have drawed a h-beam in SolidWorks, and tryed to do som stress/deformation analysis on the beam in CosmosWorks.

The ends of the beam are fixed, and the loead is on top of the beam. The load is 1000N. And I need to know how much the h-beam will deforme in inches or mm on the middle of it. Anyone who can help me with this?

Or maybee anyone have a link to a guide or tutorial that shows me how I do it?

2. Here is a picture of what i mean..

3. I don't understand what you're asking for. The chart you posted, shows the displacement. That's what the scale on the right is for. You've already done it. I can't read the top of your scale but it looks like it's deflecting about 0.06 MM.

4. Okey, now I understand. Thank you!! I didn`t look so much at that scale since I didn`t understand it. Is this the right way to convert the numbers on the chart?

5.404E-002 = 0,054 mm
1.965E-002 = 0,019 mm

But if I want to find the displacement on one specific point on the beam, example 300mm on the topp from the end. How do I find the displacement on this exact point?

• that's as simple as a small hand calculation

• Interesting link you posted. But I want to use Solidworks for this thask, and I want to find the displacement of one specific point on the beam. How do I do that?

• Be VERY careful using cosmosexpress... It's crap and very very easy to generate complete nonsense. You can't pick much in the way of boundary conditions, no control of the mesh, etc etc.

I would perform the hand calculation above ^^ even if just to check that what you calculated in cosmos makes any sense at all.

You really can't find the specific displacement at one point using cosmos express, that's one of the ways they force you to upgrade to the pro version or whatever.

Be careful and consider the ways you are constraining the ends... If you are fixing both ends, your beam is "fixed - fixed", if you look at the hand calculations, you'll notice this is entirely a different equation then if the end is supported by a roller, etc... This is because a bending moment helps resist the bending this way. Anyways, just be VERY careful using that if the results are for anything important.

The first is statement is true, its not crap, its for simple parts, most off the times the user is crap.............

• So if I upgrade to the Pro version, I can find displacemant att one singel point? Does the CosmoExpress in Pro features have allot more features?

I`m interested inn using these kind of analysis tools often. But should I select a other analysis software that is more professional than CosmoExpress?

• Yes you cann,
If you go to your Solidworks dealer he cann explain more off it and show you.

regards

• Cosmos works just as good as Ansys.

Sh!t In Sh!t out for bad data.

An H beam is normally used for vertical supports, I beams for horizontal loads.
