Abstract
The present research investigates the effect of employing large displacement in finite element modeling on the generated shakedown (SD) boundaries of thin-walled 90-deg scheduled pipe bends. A recently developed methodology termed: shakedown limit - plastic work dissipation (SDLimit-PWD) method generates the SD boundaries via employing the large displacement in the finite element (FE) simulations. Additionally, a well-established direct noncyclic technique termed: shakedown direct noncyclic technique (SD_DNT) generates the SD boundaries via employing the small displacement formulation in the FE simulations. Comparing the SD boundaries generated via both methods illustrated a marked increase in the generated SD domains due to employing large displacement.
