Figure 4: Surface profiles compared with theory.

Beads are 15 μm in radius. (a) E=500 kPa, (b) E=85 kPa, (c) E=3 kPa. The JKR theory (red curves)13 and extended JKR theory (black curves)43 are shown for W=71 mN m−1. Note the change in horizontal scale in c. For the E=3 kPa substrate in the JKR theory is shown with W=81 mN m−1 chosen to match the particle indentation (red-dashed).
