Abstract:
Objective To evaluate the usage of moir>s interferometre in porcelain-fused-metal interfacial fracture mechanics. Methods Raster was produced on the surface of samples with different thickness of porcelain and metal in 5 groups. The stripes of“field and,field under different load were collected. Then the rupture tenacity Jc~calculated and the extensions of flaws were observed. Results Stress concentration appeared around the flaws under load conditions. The stripe became denser under ~load. The rupture tenacity Jc and the direction of flaw extension of each group were different. Conclusion Moir6 inter- ferometre can be used in the study of porcelain-fused-metal interfacial fracture mechanics and to prognosticate the direction of flaw extension.
