Method & Evidence

AimTo investigate the influence of specific die design features (bridge design for hollow dies, sink-in for solid dies) on the extrusion load, temperature, velocity, and microstructure of aluminium alloy EN AW-6082 using 3D FEM simulations and experimental validation.

MethodNumerical simulation and experimental validation

Procedure3D FEM simulations were conducted using Forge2009® software to model the aluminium extrusion process for various die designs. Physically-based microstructure models were integrated into the FEM to predict recrystallized grain size, subgrain size, misorientation, dislocation density, and recrystallized volume fraction. These simulation results were then compared with experimental data obtained from extruding complex sections at the BOAL plant.

Paragraph starter

The use of advanced modelling techniques, such as 3D Finite Element Method (FEM) simulations, has been shown to be effective in predicting the outcomes of complex manufacturing processes like aluminium extrusion. Research by Nilsen (2020) demonstrated that variations in die design could be accurately assessed for their impact on extrusion load, temperature, and material flow, with simulation results correlating well with industrial experiments. This highlights the potential for using such modelling approaches to optimize product design and manufacturing efficiency by virtually testing design iterations.
