considering Lame's equation I am little bit confused about the tangential (Hoop) stress distribution and radial stress distribution.sign convention in book is different for hoop and radial. whether to take p0-pi or pi-po.

hello sir, my name is abdul haris, i came from indonesia, i wanna ask you about pipe stress analysis, from what i know stress in pipe and in cylinders almost same, my final task is about pipe stress analysis in pipe bend using Ansys and then validating with analytical calculation and the output is von mises stress, to know von mises i have to search principal stress in 3 axis, i used hoop and radial stress in your explanation, but the axial stress i use longitudinal stress which is sum of axial stress, internal pressure and moment bending, can you explain to me how to calculate moment bending in pipe bend please ? thank you sir

How is the mean diameter larger that the diameter? Shouldn't is be (100mm+150mm) / 2....... Dm = 125mm?

he wrote radius, then worked out the diameter. so the mean diameter would be ((2x100)+(2x150))/2

If I am not mistaken, your formulas for hoop stress and radial stress are wrong. The +- sign in the middle is meant to be the opposite for both.

tarun nallur are you sure about it? I could not go through the derivation that was given in the book they seemed to have different expression that was way too long. I learned the concept from this video only. So if you are sure about what you said please let know
