FIG. 6.
(Color online) Predicted bubble behavior in polyacrylamide gel: (a) the maximum bubble radius achieved during one BWL pulse for a wide range of possible gel viscosities (see Sec. III); and (b) the bubble radius history for μ = 0.01 Pa s · · · (blue), μ = 1.0 Pa s – – (red), and μ = 3.0 Pa s —, the rectangles correspond to the onset of damage.
