TL;DR: In this paper, the authors used the finite element method to explore the plastic flow pattern of a circular tube that is hydraulically expanded or crushed into a rectangular cross-section.

TL;DR: In this paper, a finite element based Inverse analysis technique was developed to determine the flow stress and friction at the tool/workplace interface simultaneously from one set of material tests, aimed at minimizing the error between experimental data and predictions made by rigid-plastic finite element simulations.

TL;DR: In this paper, the deformation zone is divided into three segments as pure elastic deflection without contact, elastic-plastic bending without contact and elasticplastic bends in full contact with the die shoulder.
