Jamming of packings of frictionless particles with and without shear

(color online) Examples of panels [(a) and (b)] configurations and [(c) and (d)] structures of strong bonds with and without shear. Panels (a) and (c) are for non-sheared systems, while panels (b) and (d) are for sheared ones. Different colors in panels (a) and (b) represent different coordination numbers (purple = 6, blue = 5, cyan = 4, green = 3, and red = 0). The color scale bar calibrates the magnitude of the bond strength. (e) Probability distribution of the angle of the bonds, P(θ). For sheared systems, distributions for all bonds and strong bonds are both shown. For non-sheared systems, the two distributions are roughly the same, so only the distribution of all bonds is shown here.
