Title  :

SHEET BENDING THEORY APPLIED TO A THREE ROLL PROCESS

Abstract :
This paper presents an analytical solution developed to compute, in an approximated form, bending moments from curvatures at different positions occupied by a specific section of a sheet being bent while in a three-roll-bending machine. The distribution of bending stresses is obtained, as well as the residual stresses resulting from springback of the component at the end of the process. Elasto-plastic conditions under the viewpoint of the deformation theory of plasticity are considered for a power law material. For a particular application considered residual stresses as well as springback is computed. Results obtained compare well with published results.
