The explosive compaction fabrication process of cylindrical uni-directional porous copper, consisting of an outer pipe completely filled with smaller inner pipes, was investigated by experimental and computational simulations to analyze and optimize the fabrication process conditions. The computational simulations were carried out using a two-dimensional model, mimicking the transverse cross-section of fabricated specimens. The computational simulation results revealed that the velocity of the outer pipe, which cannot be experimentally measured, was insufficient for explosive welding and that the walls of the inner pipes had the potential to fail depending on their initial positioning and thickness.
