|초록||This paper presents development of a finite element simulation program and analysis of hot extrusion through square dies with a mandrel. The design of extrusion dies is still an art rather than science. Die design for a new extrusion process is developed from through in-plant trials. In the presen paper, a three-dimensional steady-state finite element simulation program is developed. Steady-stat assumption is used for both the analyses of deformation and temperature. The developed program effectively used to simulate hollow extrusion of several sections. Distributions of temperature, effective strain rate, mean strain rate and mean stress are studied for an effective design of extrusion dies.
