    Strain distribution in cogging process of ingots with internal discontinuities
    (2009) Chyła, Paweł; Łukaszek-Sołek, Aneta; Sińczak, Jan
    In this paper is presented analysis of cogging process of the 16 Mg ingot in the three-dimensional state of deformation, using commercial program QForm 3D to valuate effective strain distribution. Additionally voids closing were analysed, which were purposely inserted (various diameters and shapes) in selected areas. Numerical calculations were carried out for two following processes: upsetting of the reforged ingot and cogging process. Cogging operation of reforged material was simulated according to two schedules from the head and the bottom side of the ingot. As a criterion of valuation of the cogging process with flat dies were accepted maps of effective strain distribution.
