Hi! I'm doing some research in pipe stress in ANSY, i have to model a system and compare two results. One without expansion joint and one with expansion joint. This is the first video i can actually see how to use pipe idealization, pipe temperature and pipe pressure wich are the most important things. Do you have more material about this? I can't use Caesar ii or AutoPIPE wich are the best software for pipe stress analysis, i must use ANSYS. Can u help me with that?
Hello, Thank you for video. I have question ? Why we have to change deformation scale. I am doing also pipe stress analyse like you in my project. When i want to scale true scale 1x all pipe looks like seperate from each other. What is the reason of this. I want to see real deformation, if we select undeformed i cant evaluate result properly.
In this "pipe" model it's possible insert the internal pressure and calculate the Von Mises stress in the pipe? If not where is the good way for a calculate a long pipe with internal pressure? Thanks
To calculate pipes regarding the pipe code and standards -ASME, ANSI, ASTM, AGA, API, AWWA, BS, ISO, DIN - the Von Mises stress is not necessary. Anyway, you can calculate the Von Mises stress by using a 3D-Model of the pipe using shell elements. This should be done in a little while if the model is not far to big.
When it comes to pipeline support it’s not exactly the best solution. In practice, we encounter that the pipe usually rests only on the underside. This would mean that the pipe is possible to move in all directions except downwards. This cannot be achieved with Ansys standard boundary conditions. However, it is possible to use a nonlinear spring (combin39 finite elements) but this is not the simplest solution, especially for someone who is a beginner at Ansys. If you know a simpler way, I would kindly ask you to share with us. Thank you in advance.
I imported elbow in SLD file and tried for analysis of pipe pressure like your videos but pipe pressure doesn't seen. model has to create with line in Ansys to add pipe pressure ?
No, you cant put pipe pressure on a 3D model. But if you use 3D elements or shell you just can apply the pressure on the inside surface. And dont forget to simulate the axial force by putting a negative pressure to the cut surfaces.
Could you make the meshing more fine ? Also the pipe circular section after solver shows like small hexagonal rings one after another. Could you make it more fine and lim--->a circular shape
