Ball?on?ring test validation for equibiaxial flexural strength testing of engineered ceramics

The validation of a ball-on-ring, equibiaxial flexural strength method to obtain the transverse rupture (TRS) right cylindrical ceramic specimens was performed in this study. Validation test achieved using commercially available engineered high purity alumina disks and finite element (FE) model analysis. validated fixture then used TRS Weibull statistical analysis MgO-partially stabilized zirconia (MSZ) Y2O3-partially (YSZ) disks. data for alumina, MSZ, YSZ agreed with values reported literature. A statistically relevant number samples (N > 30) each material were tested allow parameters these materials within expected ceramics. characteristic determined be 289, 786, 814 MPa, respectively. modulus between 10 25 material, which is typical In addition, FE results close agreement experimental fracture three
