FEA of Radial Stress Inside a Pipe

[Rizkyffq]

Hello all,

So i am on project to create static simulation of radial stress inside a pipe but i got little obstacle on this project due i am kinda newbie on static simulation using Solidworks.
Probably someone that expertise on solidworks static simulation may help me.

As picture above there 6 components that will generates radial stress (purple colour) to inside diameter of pipe.
I already set the fixture for the pipe at above and bottom with fixed geometry (green colour). So assume that pipe is really fixed, only 6 components that generates radial stress to surface of inside diameter.

That is schematic of phenomenon that i desired, it seems simple but for many times i tried to run this simulation always failed, maybe i have mistaken to set the connector ?

So the final result that i want maybe will become like this:

the different it just, radial stress came from the outside of pipe while in my case the radial stress come from the inside.

Hopefully someone that expertise in solidwork static simulation may help me for this case.
Thanks in advance sirs.

Can you show your results (stress distribution in your model) ? Make sure that contact between these components is properly defined.

What exactly is the question? Does the analysis abort? Or do you want to know how to display radial stresses? Or something else?

For starters take advantage of the symmetries you have you could drastically simply the model.

So the result of this simulation became like this:

And the connection/contact i used:

And as the result of simulation, seems that it's wrong phenomenon that i desired as example that a mentioned above.
The radial stress is not distributed to the wall of pipe, as you see there is no stress on the pipe and i think the simulation is failed.

i am very newcomer on solidworks static simulation, maybe someone may give me advise or tutorial a case like this ?

Your pictures are low resolution and hard to interpret but it does seem like there is radial stress in the pipe wall.

 

[FEA way]

You may have to adjust the range of contour plot (in Chart Options) to see the stress distribution on the pipe.

Hello!,
Is very easy, apparently you have rotational symmetry of both loads & geometry then you can study a portion of your model simply applying the correct boundary conditions of symmetry: displacements normal to symmetry planes are zero, either using global coordinate system or local (you can study 1/4 model). This will reduce the model size and will allow you to create quality mesh using refined mesh.
Best regards,
Blas.
