Figure 2. (a, b) Shear-induced dilation of ordered close-packed circles: (a) four circles in biaxial compression
and (b) 20 circles in pure shear. Grains are light gray, grain centroids are marked with dots, interstitial liquid is
shaded dark grey and arrows indicate the direction and magnitude of force. (c) Four globules in Al-15Cu at
~70% solid (centroids marked with dots) loaded similar to (a).
