What is Shakedown and Limit Analysis of 90° Pipe Bends Under Internal Pressure, Cyclic In-plane Bending and Cyclic Thermal Loading about?

The Linear Matching Method is used to create the shakedown limit and limit load interaction curves of 90 pipe bends for a range of bend factors. Two load cases are considered i) internal pressure and inplane bending (which includes opening, closing and reversed bending) and ii) internal pressure and a cyclic through wall temperature difference giving rise to thermal stresses. The effects of the ratios of bend radius to pipe mean radius (R/r) and mean radius to wall thickness (r/t) on the limit load and shakedown behaviour are presented.
