An Axisymmetric Finite Element Analysis of Hot Tube Extrusion for the design of Ceramic Dies

The use of ceramics for extrusion dies is limited since the modification of die design is difficult. In order to successfully apply the ceramic dies to extrusion dies, a better understanding of the process should be preceded. This study focuses on understanding the characteristics of the process. In the present study, a hot extrusion of tube with a mandrel is analyzed by ALE finite element method. In order to obtain the stress state of ceraminc dies, the elastic analysis of dies is also carried out.
