An aluminum extrusion process is simulated numerically with a computer.
In this process, a punch pushes an aluminum billet of diameter D through a die of smaller diameter d. In the computer simulation, what is the maximum punch velocity Vp
so that the net dynamic force (predicted by the simulation) acting on
the aluminum during extrusion is at most 5% of the force due to
deformation of the aluminum? Evaluate for a specific case where D = 0.10 m, d = 0.02 m, and the density of aluminum is ρ = 2700 kg/m3.
