THE APPLICATION OF THREE-DIMENSIONAL COMPUTER SIMULATION WHEN DEVELOPING DIES FOR EXTRUSION OF ALUMINIUM SHAPES

摘要

The automated system of three-dimensional computer simulation with use of FEM is developed. The model is based on the Euler approach. The function of Markov variation principle is used for derivating. The connected task of thermo-viscous-plasticity is solved. The flat die is designed for extrusion of the thin-walled shape from a soft aluminium alloy 6060.
