Using finite element and polycrystalline plasticity modeling, we explore the influence of die
design and material behavior on the extrusion of bimetallic tubes. Three distinctly different …

In direct extrusion of aluminum alloys, billets are discretely loaded into the press and joined
by the high hydrostatic pressure field. The contamination of the billet-to-billet interface by …

The steady state extrusion process of a large, multi-cavity aluminum profile for high-speed
train was simulated using the Arbitrary Lagrangian Eulerian (ALE) algorithm. The simulation …

The numerical simulation of extrusion process for complex hollow magnesium doorframe is
carried out using HyperXtrude software. According to the simulation results, the extrusion die …

Resource and environment problems will be the bottleneck of sustainable development in
the future, which is significant influence for the transport industry. Therefore, the low fuel …

An experimental investigation was made on the effect of die angle on the quality of extruded
product ie surface finish and hardness of cold extruded aluminum. The semi die angle (α) …

This work describes the procedure for the design of a multi-hole extrusion process. For the
same sizes of the holes, the ram force in a single-hole extrusion process is more than in a …

In this study, a general methodology has been developed to design the proper bearing in
order to eliminate the curvature of the final product in extrusion process. Three smooth …
