Investigation of Bending Characteristic of 5XXX – Series Aluminum Alloys

Abstract

In this study, strains and fraction formation which occur in the parts was examined by creating a bending simulation in the MSC.Marc finite element analysis program for En AW-5083-H321 series of aluminium which are more frequently used in industry. According to the literature, such studies have been conducted with the MSC.Marc finite element analysis program. Similarly, there are many fracture models in the literature. In this thesis analysis was made by selecting the appropriate fracture model which is Cockroft-Latham in order to detect the cracks on the material. After the bending analysis, pieces were bended and crack dimension was measured by microscope with the help that parameters of fracture model were determined. Fracture model parameter that has been determined was applied on different thickness with different bending radius with the help of that fracture model parameters was verified. With this study, it is aimed both minimize failures which may occur while bending and help for the reducing the standards dependence.
