Abstract

The stability of two-dimensional foam comprising bubble rafts constrained to a fixed area of liquid surface has been examined. It is found that a perfectly sixfold-coordinated foam is unstable against loss of cohesion, the foam breaking after some 20 min to leave a significant surface area free of bubbles. Foams containing a single dislocation or point defect are stable against such breakage. It is argued that it is bubble deformations induced by the elastic stress fields around the defects which are responsible for this stabilization.
