โœฆ Synopsis

Using an empirical friction characteristic for urethane under pressure, an approximate theory for determining the initial yield pressure and the final forming pressure needed on an internal urethane rod to bulge a tube is put forward. The results of experimental investigations agree well with the theoretical predictions for aluminium tubes.
