    Applying pressure equation on pipe external surface

    Greetings! Need help for applying non-uniform pressure distribution on a pipe outer surface. It seems that I have to use the advanced load method in FEMAP 9.1, but I am not sure how to do it. Pipe geometry: A thin-walled pipe (Dia=4', thickness=1"). It is externally pressurized with...

    External pressure for underground pipe

    Thanks BigInch, Unfortunately it is not made of steel. it's like a rubber (but not really rubber - more durable). And the diameter is about 4ft so that it makes a thin-wall structure. Due to its flexible nature, the external pressure is very important (Internal pressure assumes atmospheric)...

    External pressure for underground pipe

    Dear all, I have a pipe that is buried underground 10' below from the surface. Say, the diameter of the pipe is 4' and thickness is 1". Since it is buried, the external pressure, due to soil weight or tranportations etc, around the pipe won't be uniform. Is there any pressure formula that can...

    Relation of Hoop and Compressive (Tensile) Stress

    Greetings all, Is there any relation between hoop stress and compressive (or tensile) stress? Specifically, can hoop stress be derived from the aforementioned stresses? Thanks Sotree
