Abstract
The curved die plays a significant role in reduction of extrusion load, refinement of microstructure and improvement in quality of product. In the present investigation, a numerical FEM modeling has been carried out for extrusion of triangular section from round billet through a curved die using DEFORM-3D software for steady state deformation using rigid plastic material. The extrusion load has been predicted. The effective stress, strain, strain rate velocity and temperature distribution have been determined. An experimental test rig has been fabricated. The experimental results are compared with the theoretical results. The results of computations are found to be in good agreement with those of the experiments.
