Stress analysis of compression of aluminium with rotating tools
conference contribution
posted on 2004-01-01, 00:00 authored by X Ma, Matthew BarnettMatthew Barnett, Y KimCompression tests carried out on aluminium specimens showed that when the die was rotated the compression load dropped. A slab method is employed to examine this process. The load reduction is explained by the deviation of friction vector due to the relative circumferential movement between the die and the material. This mechanism is incorporated into a theoretical model and an expression is derived for compression pressure. Analytical solutions established compare favourably with experimental results. It is also shown that there is a limitation to the load reduction: the compressive load can never be lower than 70 percent of the yield limit.
