I don't think they are doing this right. ASME more recently very specifically stated that only elements to use is brick elements. Apparently there seem to be underestimation of bending stresses due to geometry of the triangular elements. Also if at all there are no other ways, and you are stuck with Inventor for stress linearization, it would be good to provide a partition along the thickness in the normal direction. In that way you can have more nodes along the thickness. Just two node and one element like they showed here is not enough for level of conservatism we follow while designing pressure vessels.
Thank you for sharing the useful knowledge. Great work!
Glad you enjoyed it, you are welcome! KETIV | Nicole Morris
Thanks for the video.
Question: How do we apply a load due to the fluid weight inside the tank?
just select the inside surface, instead of external.
very useful, can you make more linearization analysis. for the machine members. thank you.
Thanks, we will pass this suggestion onto our team!
