Dome Reversal of Metal Beverage Containers

Abstract

Dome reversal in metal beverage containers refers to the event when the dome at the bottom of the containers snaps through due to overpressurization. This paper presents a combined experimental and numerical investigation of the problem. The response of the bottom of the containers considered is primarily axisymmetric prior to buckling and is characterized by a limit pressure instability. Under volume-controlled loading, collapse in an asymmetric mode occurs shortly after the limit pressure is achieved. An axisymmetric model of the problem was sufficient to calculate the limit pressure for the case considered. Results from a nonaxisymmetric model indicated that asymmetric modes became dominant after the limit pressure had been achieved.
