Fig. 6.24. Schematic diagram showing the geometry of fibrous fringes developing in simple shear matrix flow in the case of spherical and
cubic core-objects, and for rigid and deformable fringes. The situation for cubic core objects is shown for only one initial orientation of
the cube, and can be different for other initial orientations (see Fig. 6.22)
