Ideal Flow Design of Plane-Strain Bending Driven by Springback

The present paper is concerned with the design of plane-strain bending wide sheets driven by sheet’s geometric shape after unloading. solution based on ideal flow theory. It determines loading path (the dependence between dimensionless moment and tensile force) that produces desirable shape. theory valid for rigid perfectly plastic material model. A method proposed in literature combines a at an elastic springback. final practically analytical. numerical only necessary to solve system transcendental equations. An illustrative example provided. This shows that, some cases, it sufficient use determine accurate
