Stress banding in compressed quasi-two-dimensional aqueous foams

We present results from a study of the compression of a quasi-two-dimensional aqueous foam in a Hele-Shaw cell. Our results show that during compression, the spatially averaged normal-stress difference localizes in bands with a wavelength of the order of the mean diameter of a bubble. Stress field c...
