Establishment of Bending Analysis Technique on the Extrusion of Aluminum Alloy

알루미늄형재 압출에 대한 굽힘 해석기법 개발

Two angle-shaped extrusions have been studied in order to analyze the bending effect of the extruded product using the three-dimensional rigid-plastic finite element method. The velocity distribution at the outlet becomes the source for the construction of the bending configuration of the final product. in which an analytic scheme has been developed for the description of the bending. A systematic approach presented here appears to have sound agreement with the experimental result, and has been applied to a large extrusion of aluminum alloy.
