It is shown that dilatancy (a change in liquid fraction due to shear) can be a large effect in foams. Theory and simulations for the standard idealized model of a two-dimensional liquid foam are found to be in good agreement. The estimate of the maximum effect of static shear at constant osmotic pressure gives an absolute increase in liquid fraction of roughly 1.5%, halfway between the wet and the dry limits. The same theory, which uses the established dependence of shear rnodulus on liquid fraction, predicts a qualitatively and quantitatively similar behaviour in three dimensions.
