FIG. 1.

Several cases of channel cracks in a three-layer coating.

FIG. 2.

Reduction in the elastic energy associated with a crack advancing a unit distance, , is calculated from the elastic energy stored in a slice of material of unit thickness far ahead of the crack front minus the elastic energy stored in a slice of material of unit thickness far behind the crack front.

FIG. 3.

Normalized critical strain as a function of the normalized thickness of the organic layer for cracks in inorganic layers.

FIG. 4.

Normalized critical strain as a function of the normalized thickness of the organic layer for a crack through the entire thickness of the coating.

Image of FIG. 5.
FIG. 5.

Comparison of the critical strains for several cases. The hatched area is the safe region, i.e., with no crack propagation in the coating. An optimal thickness exists [in the part of the safe region bounded by the normalized critical strain for case (c)], for which the multilayer coating can sustain the largest applied strain.
