Abstract
In this paper, in order to investigate the creation of macroscopic shear bands, due to material flow tracks in the cross section of a wire after flat rolling, the combined Finite and Slab Element Method (FSEM) is used. The effective strain field is predicted for different reductions in height. The validity of the method is assessed by performing the Vickers microhardness measurements on the cross section of the flattened wire. It is found that the FSEM and microhardness results show the minimum and the maximum effective strains at the round edge and the center of the flattened wire, respectively. Also, the results indicate two bands of maximum effective strain in the cross section of the flattened wire being in consistent with the two macroscopic shear bands observed after metallographic examination.
