Pipeline stress and strength problem

[Willy Lawson]

Hi everyone,

i am new to this and am struggling badly on a distance learning module for Subsea technowlogy.

The question is.

Find the equation for equivalent stress for a 3 dimantional stress regime? and when would this equation be required?

I really would apreciate some info on this, i am in the dark.

Thanks in advance

Willy

Perhaps try http://answers.yahoo.com/question/index?qid=20070805164332AAvCDof". It would be needed when you have stress (force) applied in more than one direction on ductile materials.
