Supplemental Material for "Athermal shearing of frictionless cross-shaped particles of varying aspect ratio" by T. A. Marschall and S. Teitel The Supplemental Material consists of a set of animations showing the shearing of various configurations discussed in the paper. In the list below the file name of the animation is followed by a description of the system shown. The files are listed in the order in which they are discussed in the paper. p80_dg1e-05_b1-4.mp4 Shearing of a system of N=512 crosses with aspect ratio beta=0.25 at packing fraction phi=0.80 at strain rate gdot=1e-5 p70_dg1e-05_b1-1.mp4 Shearing of a system of N=512 crosses with aspect ratio beta=1 at packing fraction phi=0.70 at strain rate gdot=1e-5 p75_dg1e-05_b1-2.mp4 Shearing of a system of N=512 crosses with aspect ratio beta=0.5 at packing fraction phi=0.75 at strain rate gdot=1e-5
