Showing cut plane in clip

AmirMar

Hello,

 

I have a relatively large bulky part with many internal holes. I need to view the stress field inside the structure and not on the outer surface.

I tried to use the 'Clip assembly with with a plane' but it doesn't work well. I don't see the cut-plane surface, only the outer surfaces.

I tried to search for this option in the documentation but I couldn't find anything.

 

Is it possible to do that in Simsolid?

 

Thank you,

Amir

Hi Amir,

 

Currently, only surface stresses can be plotted. Internal stresses are not available at this point.

Thanks,

Girish

If you need the internal stresses, then model the part in multiple parts which are connected at their boundaries.

In my experience this is not a solution. If you split a solid and then connect the internal boundaries you lose internal continuity. The 'connection' is usually implemented (internally to the FEA software) with linear constraint equations.

That is your experience with traditional FEA. Try it

I tried a simple case of a notch on a flat bar subject to traction (above: a single solid, and below: the solid split in correspondence of the notch).

It is quite apparent that the splitted solid results are different. The connection between the two parts perturbs the solution.

I did a check myself with these parts

and found no big changes in stress

please recheck your results and input.

I really wondered internal stress and I tried to your method which you have tried to see internal stress as well.

 

1)

 

-400x100x10mm - Material is 'steel' from Simsolid Generic Materials Library.

 All connections are 'bonded'

<?xml version="1.0" encoding="UTF-8"?>

 

-I applied 750 N to each notch

<?xml version="1.0" encoding="UTF-8"?>

 

-Here is the distribution of Stress from front view. There is a bit different.

 

-Here is the internal stress graphic from inside surface

<?xml version="1.0" encoding="UTF-8"?>

<?xml version="1.0" encoding="UTF-8"?>

 

-This result from non-split side. As for me, both results are almost the same.

2) Another work, on the same condions , you can see the distribution of stress .  There is a bit difference.

 

-Splited one

 

-One-piece
