Figure 6

Schematic demonstrating the strain (ε) and stress (σ) distributions in a ceramic plate on a compliant substrate, loaded axially from the top surface with a hard spherical indenter. Illustrations are made for (a) strain and (b) stress distributions in a homogeneous Y-TZP plate, and (c) strain and (d) stress distributions in a graded G/Z/G plate on compliant substrates along the loading axis across the plate cross section. LA and NA stand for load axis and neutral axis, respectively. Note in (d): the maximum tensile stress at the bottom surface of the G/Z/G plate is lowered relative to homogeneous zirconia (b).
