Abstract

Abstract: In the press shop of most sheet metals, sheet material undergoes complex strain path and also the formability of the sheet material was limited by the stretchability of the material. Therefore, the precise prediction of path-dependent FLD based on M-K approach using generalization of Hill's 1979 anisotropic yield criterion and introducing a strain gradient effect in the constitutive equation. Also, the theoretically obtained FLD will be compared with experimental data for steel sheets.
