Simulation of the Consolidation of a Porous Material in a Combined Rolling–Extrusion Process

详细

The combined rolling–extrusion of a porous aluminum billet is simulated mathematically using the finite-element method and QFORM V8 software. A three-dimensional problem statement with one plane of symmetry is used. The fields of displacement rates, stresses, temperatures, strains, and density are plotted. It is concluded that the distribution of these parameters is asymmetric about the processing axis. It is revealed that the density achieved in the process is close to that of the compact material.
