    Bending stress in a ring

    @roby That's weird because the ring I have to calculate has a width (length) of 0,26m the obtained bending moments are around 10kNm which is very small.

    Bending stress in a ring

    I think it's impossible to combine 2 loads. If i calculate W in table 9.2 point 5 (roarks formulas) with the 480kN circumferentially distributed load and further on the bending stress with the obtained result bending moment I become results 3 to 4 times higher than my FEA analyse with autodesk...

    Bending stress in a ring

    Are you sure everything is correct in the legend cause the bending moment M is in kNm/m. Shouldn't be kNm?

    Bending stress in a ring

    @robyeng what is the meaning of the M and N in the tables. Do I have to multiply these with other values?

    Bending stress in a ring

    Ah OK thanks, I'm gonna try this with roark's formulas, if I have problems calculating this stress with this (and probably it will :p) I'll ask you again. Thank you in advance.

    Bending stress in a ring

    This is a picture of the dryer. The problem with Roark's formulas for rings is that the force C is not there. The force is the weight of the dryer and this does not just push in the middle the ring downstairs but the force is also present everywhere in the ring not just on the upper point.

    Bending stress in a ring

    I can't find any formulas for my problem. I work on a purification dryer who's fit in 2 large rings. Each ring roles on 2 rollers each make a angle of 28° with the vertical axes. The rings have an internal diameter of 2568mm and an outside diameter of 2848mm. It has an rectangular section 260mm...
