Primary stresses are often controlled within the permissible stress range and elastic design. Secondary failures are caused by fatigue damage to elbow
One failure was caused by a pressure-bearing problem in the pipe, which led to bursting and weighing problems, which in turn led to collapse.
There are three types of failure, primary failure, secondary failure and stiffness failure, all three of which are possible for buried pipes, and prim
