A simplified theory is derived for internal buckling of a multilayered structure. The layers, alternately competent and incompetent, are subject to a horizontal compression and confined between two rigid straight boundaries whose vertical separation varies with the amount of horizontal compressive strain. For purely viscous materials, the dominant folding wave length is expressed in terms of the viscosity ratio, the number of layers, and their thickness.
