Abstract: Hill's theory of plastic anisotropy and total strain theory are applied for the analysis of forming loads and stress-strain distribution in the tube-flaring with rotary punch. The calculated result-is in good agreement with the experimental result. This research will provid a design basis for application of the tube-flaring with rotary punch.
