Abstract: A new approximate solution to thickness reduction of plastic bending sheet is presented by considering the characteristics of deformation and stress distribution. The proposed method is based on the incremental theory, and volume invariance and planar cross-section are assumed. As a calculation example, the sheet reduction ratio and the distance from the neutral plane to inner boundary are calculated and compared with published data. A fairly good agreement is obtained between the calculated results and the experimental data.

Key words: sheet bending forming, thickness reduction ratio, perfect plasticity
