Friction models of kink-banding in compressed layered structures

An earlier prototype model for kink-banding in constrained layered structures, compressed in a layer-parallel direction, is summarized and extended. Important ingredients include layer-parallel stiffness, interlayer friction, overburden pressure and layer bending stiffness. The Maxwell stability criterion is proposed as a useful lower bound for failure loads and displacements. Predictions of angle of rotation, band orientation across the layers, kink band width, and initiation and propagation loads, are compared with simple preliminary small scale experiments on confined specimens comprising layers of paper.
