Elementary Elasticbending theory requires that bending stress varies linearly with distance from the neutral axis, but plastic bending shows a more accurate and complex stress distribution.
Cyclic plastic strains are analyzed for the pressurized elbow subjected to symmetric out-of-plane bending with finite element method (FEM) and the assumption of elastic-perfectly plasticity (EPP).
