Abstract - This paper deals with a metal forming process leading to a conical extension of circular cylindrical shells (tubes). This forming process is called flaring. Analytical expressions are derived for determining stress and strain fields as well as the force required for driving the expansion. The results are compared to finite element solutions and show reasonably good agreement.
