Öğe MATERIAL FLOW ANALYSIS OF BIMETALLIC HOLLOW DISC UPSETTING(Czech University Life Sciences Prague, 2016) Ayer, O.Bimetallic materials have a growing area of usage and named a type of composite materials with combining advantageous features of two different materials. Upsetting of discs obtained by aluminum and copper was studied. The FEM method was used to simulate the process and results were compared with experiments by taking material flow into account. It was determined that material flow increased with height and reduction rates and on the middle axis the material flow was highest. On the interfaces of sleeve and core materials separation after forming was not observed. Also, it was understood that simulation results of bimetallic disc sample obtained with FEM based DEFORM-3D software in upsetting procedure were in concordance with experimental results and FEM model can be useful for future studies.
