FIG. 1.

Channel cross-sections with (a) equilateral and (b) concave triangle geometries. The collapsed (c) equilateral and (d) concave channels when pressure is vertically applied on the surrounding elastomer. The scale bar corresponds to 1 mm.

FIG. 2.

Representation of a (a) wedge and (cylindrical) indenter used to model the penetration of the channel side walls into the channel based when pressure is applied to the surrounding elastomer.

FIG. 3.

Theory (–), FEA (– –), and experimental data ( ) for a equilateral triangle cross section; E = 125 kPa, ν = 0.5, and w = 4 mm.

FIG. 4.

Theory (–), FEA (– –), and experimental data ( ) for a concave triangle cross section; E = 125 kPa, ν = 0.5, and r = 4 mm.

Image of FIG. 5.
FIG. 5.

FEA images depicting the (a) undeformed and (b) deformed equilateral triangle cross section, and the (c) undeformed and (d) deformed concave triangle cross section. The scale bar corresponds to 2 mm.
