Axisymmetric compression tests on solid composite (LM6/SiCp) cylinders under various lubrication conditions and aspect ratio (height/diameter), suggest that the resulting curvatures of the barrels formed fit closely to circular arcs, the radii of which follow a power law with respect to the true axial compressive stress. The true compressive stress-strain curve obtained from the experimental data shows that of all the lubricants tested the specific forming energy is minimum for a teflon sheet type lubricant.
