Thermal Stress analysis on Pipe Elbow | ANSYS workbench tutorials for beginners

[@uujj5588]

Thank you for sharing tutorials! It is so helpful for me. But, I have a question, 3:32 How can I choose only surface or line not geometry? I wanna choose inside surface not all body... and the scoping method is Geometry Selection. so can I choose only geometry(= full body?) Thank you for your cooperation!!

In that case, you can do the analysis under steady state thermal module.

Hi, Thanks for the video. I have a brief question, the stress simulated, is higuer than the maximum allowed by ASME. How can I show my results? Thanks for your kind response

First, if you want to reduce the stress, altering the geometry of the component can significantly reduce stress concentrations. This can be achieved by adding fillets to sharp corners, increasing the cross-sectional area, or redesigning the component to distribute loads more evenly. Additionally, increasing the thickness of parts where high stress is observed can help distribute the load over a larger area, thereby reducing stress. Also, using materials with higher yield strength can help the component withstand higher stresses without deforming or failing. If it is not possible to make these changes, present the results as they are and conclude that the design will fail under the given conditions. Additionally, suggest ways to mitigate the high stress levels, such as adding supports or braces, and using high strength materials.

I have a question about your video. Perhaps you set the pressure considering the flow in the pipe. If we consider flow, shouldn't we consider not only the internal pressure but also the temperature of the fluid and the film value for convection between the fluid and the inner wall (convention conditions)?

[@themechanicalengineer]

Yes but here I have considered a constant temperature increase throughout the geometry. We can also specify the internal flow temperature then it comes under Fluid Structural Integration (FSI).

[@ChanghoKim-y7l]

you mean is that if we consider fluid we must set the convention condition and temperature, pressure but you only consider constant increasing temperature so did you not set the convention condition?

[@ChanghoKim-y7l]

i think must set the convention condition

[@themechanicalengineer]

Yes.. for accurate analysis we must set... As it a basic level tutorial I have considered a constant temperature increase...

[@김창호기계공학과]

However, to use FSI, shouldn't Fluent analysis be done first?@@themechanicalengineer
